In a deleted scene near the beginning of the film, it is mentioned that Dr. Crusher is preparing to leave for Starfleet Medical. This further adds to the sense of the ship emptying, and further cements this as the final Next Generation film.
In an interview given years after the film came out, Tom Hardy said that he took the film role very seriously, as it was intended to be his big break. The commercial failure of the film, and the response from long-time fans, apparently led to his relationship dissolving, his turning to alcohol, and considering suicide. It was only when he pulled himself together, and starred in Bronson (2008), that he got over the film.
The film's cast, in particular, Jonathan Frakes, Marina Sirtis, and LeVar Burton, have leveled fierce criticism at Stuart Baird over his direction of the film, claiming he hated the Star Trek universe, and knew nothing about it. Baird, for his part, expresses his frustration in the DVD commentary at having to tell a story in an established universe with pre-existing design and character relationships, hated having to utilize recycled sets and props, and had trouble remembering the names of the main cast.
Midway during shooting, the Captain's chair from the bridge set disappeared, apparently stolen. While the film crew scrambled to find a way to work around the problem, the Star Trek: Enterprise (2001) cast and crew shooting in the soundstages next door decided to have a little fun at their franchise-mate's expense: Scott Bakula visited Patrick Stewart's trailer to present him with a makeshift wooden "replacement" chair with the letters K-A-P-T-I-N painted on it.
It was generally believed that Jeri Ryan (Seven of Nine from Star Trek: Voyager (1995)) was offered a cameo in the earliest draft of the movie's script, but was unable to commit when she got a role on Boston Public (2000). The cameo was supposedly given to Kate Mulgrew (Admiral Kathryn Janeway) instead. However, during a 2014 Star Trek convention, Ryan admitted that the studio had offered her a much larger role, which would have replaced an unspecified character in the film. She passed on the opportunity, not wanting to take a break from Boston Public (2000) already, and also out of fear of being typecast. But her biggest concern, was that her presence in the movie would make no sense, as her character didn't know anyone from the Next Generation crew. The studio then offered her a cameo as a guest at Riker and Troy's wedding in the beginning, which she also refused because that would make even less sense. A cameo for Admiral Janeway was created instead.
After Star Trek: Generations (1994), Michael Dorn (and thus Worf) joined the cast of Star Trek: Deep Space Nine (1993), and since then his character has been a source of awkwardness. In Star Trek: First Contact (1996), Worf pilots the Defiant, he is beamed aboard the Enterprise-E after the Defiant is no longer able to move. In Star Trek: Insurrection (1998), Worf is asked why he's aboard the Enterprise-E and away from Deep Space 9; his explanation is literally interrupted. Also, Worf's most notable feature in Insurrection is getting a pimple. For this film, in an earlier script Worf is asked why he isn't too busy with ambassador duties, which were given to him in Star Trek: Deep Space Nine: What You Leave Behind (1999). He drunkenly replies that he was not suited for diplomatic life.
Aside from the explosions, the ramming of the Scimitar by the Enterprise is not computer-generated. The filming crew actually ran a model of the forward saucer into a model of the Scimitar, shot it in slow motion, and hung it upside down to give the illusion of the hull flotsam drifting into space.
Nicholas Meyer was approached to direct the film by Rick Berman, but told Berman that he would want to do a re-write of the screenplay. Berman was forced to refuse, as he had already promised John Logan full control over the screenplay, and so Meyer respectfully turned the offer down. Berman next considered offering LeVar Burton the chance to direct, but was then ordered by the studio to hire Stuart Baird.
Every previous Star Trek series gets some sort of mention or reference. There is a maneuver named for Captain Kirk from Star Trek (1966). There is mention of the Dominion War from Star Trek: Deep Space Nine (1993). Admiral Janeway, from Star Trek: Voyager (1995), has a cameo, and one of the ships that the Enterprise was to rendezvous with, is the U.S.S. Archer, named for the Captain in Star Trek: Enterprise (2001).
According to his interview in the DVD's special features, Sir Patrick Stewart did all of his own driving for the ARGO scenes, with the exception of the opening shot leaping out of the shuttle and the subsequent sharp turn.
In one deleted scene, in which Picard and Data discuss the concept of family (and emotions toward family), Data cradles a small flute. The flute is a treasured item of Picard's from Star Trek: The Next Generation: The Inner Light (1992), widely considered as one of the best of the series. In it, Picard lives out another life and raises a family of his own in a condensed, simulated reality. The flute prop was often visible in later episodes of Star Trek: The Next Generation (1987), during scenes in Picard's quarters. It sold at a "Christie's" auction for 48 thousand dollars, along with other items from forty years of Star Trek memorabilia.
Wil Wheaton (Wesley Crusher) was invited back to the cast by Rick Berman, after Wheaton spoke with LeVar Burton (Lieutenant Commander Geordi La Forge) on a special Star Trek edition of NBC's The Weakest Link (2001). Wheaton remains in the end titles, although all of his scenes were cut from the final version of the film, and he can only be seen as a non-speaking extra during the wedding scene.
Shinzon's ship, the Scimitar, resembles a lionfish when extending its tines to use its radiation weapon. Picard, for many years, had a lionfish in an aquarium in his Enterprise-D ready room in Star Trek: The Next Generation (1987).
There is a persistent rumor that Michelle Forbes can be seen reprising her Star Trek: The Next Generation (1987) character Ro Laren (who defected to the Maquis) during the wedding reception. It is claimed that she is the dark haired woman seen smiling behind Guinan (Whoopi Goldberg) during Picard's speech. This actress is not Forbes.
Originally there was to be a follow up to the film, which would have seen the Enterprise crew crossing over with characters from Star Trek Deep Space Nine and Star Trek Voyager, as well as featuring Riker's ship The Titan and it's crew members. Those plans were scrapped due to the poor box office reception to Nemesis.
The Enterprise Bridge, Ready Room, observation lounge, engine room, and some of the corridor sets are the only pre-existing sets to remain from previous films, as sets such as the transporter room, sickbay and crew quarters were reused from Star Trek: Voyager (1995). For this film, new crew quarters sets, similar to the ones seen in the previous film, but more detailed, were built, along with a new sickbay and science lab set.
Second time that Counselor Troi assumes the helm position of the Enterprise in a Star Trek movie. The first time was in Star Trek: Generations (1994). Both times, the Enterprise had been (or was about to be) heavily damaged.
The blue beverage seen in the Shinzon - Picard dining room scene is Romulan ale. It is illegal in the Federation, because of its highly intoxicating properties. Despite this, Romulan ale has been featured in many Star Trek stories, and possessing it, is akin to having Cuban cigars in modern times.
The earliest version of the script was written so that Sir Patrick Stewart would have been playing both Picard and Shinzon, and the final battle between the Enterprise and the Scimitar took place in orbit of Earth.
Shinzon is an actual Chinese name, chosen by writer John Logan as it continues the trend of Chinese names for Romulan characters (as well as the new Reman characters). Logan admitted that he has absolutely no idea what the name actually means.
The ARGO buggy was designed and built by ProTruck Racing Organization, founded by off-road racing champion Ivan "Ironman" Stewart (no relation to Sir Patrick Stewart). Ivan Stewart appears in one of the DVD special features.
The ships backing the Enterprise in Federation territory according to Data (Brent Spiner) and Picard's (Patrick Stewart) meeting in stellar cartography are, U.S.S. Intrepid, U.S.S. Valiant, U.S.S. Galaxy, U.S.S. Aries, U.S.S. Nova, U.S.S. Hood, and U.S.S. Archer (named for the Captain in the prequel series Star Trek: Enterprise (2001)).
The knives used by Shinzon were all designed by Gil Hibben, an American knife-designer, who also designed the Rambo III (1988) knife. The knives used in "Nemesis" were not specifically designed for the film. All of the designs used are at least ten years old.
According to Brent Spiner in an August 24, 2012 Canadian convention, he went to Capitol Records and recorded the whole song "Blue Skies" in studio A, and he was also filmed singing the whole thing in the film, but they only used a small part of that scene.
This film features references to every Trek show before and after Next Generation. Riker orders a manuver Kirk epsilon, for Capt. Kirk One of the ships waiting for the Enterprise is the USS Archer, named after Capt. Archer from Enterprise Admiral Janeway makes a cameo giving Picard his orders Worf returns from DS9, in a deleted scene he claims he was not cut out for Ambassador life, referencing the end of the DS9 series when he was promoted to ambassador with Chancellor Martok
During the film series, the Enterprise-E deck structure has changed multiple times. In First Contact, Picard states the are 24 decks, yet a security officer states the borg controlled deck 26 to 11, and in this, during the battle with the Remans, the ship loses shielding on Deck 29, allowing the Remans to board.
Marina Sirtis nearly didn't return as Deanna Troi for the film due to negotiations not going smoothly and Marina Sirtis was threatened to be fired from the film and replaced by Jeri Ryan as Seven of Nine from Star Trek: Voyager (1995).
The film takes place fifteen years after Star Trek: Encounter at Farpoint (1987). Incidentally, the film was released fifteen years after Star Trek: The Next Generation (1987) first premiered on television.
Majel Roddenberry was unable to make a cameo as Lwaxana Troi for the wedding scene. Gene Roddenberry's widow was busy working on the television series Andromeda (2000), of which Majel was the Executive Producer. Gene Roddenberry created the show, and came up with the idea for the series in the 1970s, but the series did not get made or hit television screens until nine years after his demise in 1991.
Bryan Singer: Guest appearance by the man who directed Sir Patrick Stewart in X-Men (2000), X2: X-Men United (2003), and X-Men: Days of Future Past (2014). He is the crew member who takes Worf's place at the Tactical console.
After first reading the script, Marina Sirtis began crying and called Brent Spiner, extremely upset of over the death of Data. Spiner jokingly reminded her that "Data's a fictional character. I'm still alive."
Brent Spiner has claimed he wanted Data to die at the end of the film because he had visibly aged out of the role of an ageless android. However, following the release of Star Trek (2009), Spiner revealed that had there been another film starring the cast of Star Trek: The Next Generation (1987), Data would have been brought back.
After Data's demise, Picard and the Enterprise crew makes a toast to Data by quoting "To absent friends". This is the second time in the Star Trek films where the Enterprise crew toasts to a deceased crew member. The first time it was Star Trek III: The Search for Spock (1984), where Kirk and the original crew honors Spock by toasting "To absent friends" after Spock died from radiation poisoning, repairing the warp core.
Scenes deleted from the end of the film would have introduced Steven Culp as Commander Madden, Riker's replacement as the Enterprise's first officer. Culp later appeared as Major Hayes in the third season of Star Trek: Enterprise (2001).
It is implied in the film that Data would become the new First Officer after Riker was promoted to Captain. However, there is a deleted scene where a younger officer is on the bridge, claiming he will be the new First Officer. This scene was left out most likely to give Data more recognition.
When in Picard's quarters, the toast they drink to spoken by Picard is "To absent friends", in reference to Data. Admiral Kirk offers the same toast near the beginning of Star Trek III: The Search for Spock (1984), in reference to Spock.
The film bared some similarities with Star Trek II: The Wrath of Khan (1982): Picard, Data, and Worf discover B4 on a desert planet in the Kolaran system. Shinzon, a clone of Picard was created by the Romulans in a genetic experiment, and the Romulans exiled him to Remus. B-4 is revealed to have been put on the desert planet by Shinzon and used as a bait to lure Picard to the planet. The Enterprise battles the Scimitar in the Bassen Rift, and Data sacrifices his life to save the Enterprise crew. The film was released twenty years after Star Trek II: The Wrath of Khan (1982).
