Arnold Schwarzenegger wanted the film to be PG-13 so it would appeal to a broader audience. Being executive producer (for the first time) he approved script, director, cast, studio financing, distribution, marketing, budget, PR firm, planning a foreign release, etc. Schwarzenegger enjoyed the added responsibility because he could be involved in every facet of production.
Has the distinction of being the first film to be advertised in space. For $500,000, the film's title was graffiti-ed onto the side of an unmanned NASA rocket which was launched into space by Arnold Schwarzenegger.
Just after Frank's house explodes, the black cop says, "Two days to retirement" as a nod to Danny Glover's character in Lethal Weapon (1987). At that point, you can hear a soundtrack excerpt from the Lethal Weapon theme in the background.
One major reason for the film's box office failure was the unforgiving process needed to have it ready for the studio-mandated June 18, 1993 release date, which left almost no time for follow-up editing or fine-tuning after a disastrous May 1st sneak preview. There were discussions about moving the release into July or August 1993, especially when Universal deliberately chose to open Jurassic Park (1993) on June 11th, but it was decided that doing so would turn off potential moviegoers. When the film was released and received widespread criticism, an anonymous movie worker said "We shouldn't have had Siskel & Ebert telling us the movie is ten minutes too long".
The merchandising people came up with some Jack Slater action figures with guns, but Arnold Schwarzenegger vetoed the idea since Last Action Hero (1993) was a warmer, more cuddly action film. The film had seven video games, a $20,000,000 Burger King promotion, a $36,000,000 theme park ride, NASA's first paid ad in space, as well as a four-storey inflatable Jack Slater at Cannes and Schwarzenegger gave 40 TV interviews and 54 print interviews in 24 hours, setting a new personal record.
"Jack Slater" when trying to pose as Arnold Schwarzenegger in the "real world" keeps getting the name wrong, and calling himself "Arnold Braunschweiger." The first part of Arnold's real name, "Schwarz," means "black" in German, while the first part of his wrong name, "Braun," means "brown" in German. Also, a "Braunschweiger" is a type of liverwurst made in Braunschweig (or Brunswick), Germany. In the German dub he calls himself "Arnold Beckenbauer" ('Pool-Builder').
When Danny is arguing with Slater over checking to see if Benedict is dead after the two play chicken, he makes a reference to a villain in Die Hard (1988) (also directed by John McTiernan) who comes back at the end of the movie after being presumed dead. Shortly after, you can hear a soundtrack excerpt from the Die Hard theme in the background.
The film ran behind schedule, so much so there was just one test screening that ran for two hours and 20 minutes with a lot of inaudible dialogue, boring the audience. The studio refused to delay the opening, so not to send the message the film was in trouble, a decision Arnold Schwarzenegger agreed with.
During the shooting of the movie, Arnold Schwarzenegger gave an interview on the set to Dagmar Koller, a famous Austrian musical-star, for an Austrian television show. After the interview Schwarzenegger invited her to appear in the movie. She can be seen in the police headquarters as Danny talks to her.
At one point, Danny produces a piece of paper with a word (presumably the f-word or some variation) written on it and asks Slater to say it; Slater refuses, and Danny cites this as yet more evidence that they are in a film, as the f-word was not allowed in PG-13 films at the time the movie was made. However, the f-word does actually appear in the movie, spoken by Lieutenant Dekker during one of his rapid-fire rants at Slater. Due to the nature of the scene it is hard to discern, but it is definitely there.
Director John McTiernan said the film began as a wonderful Cinderella story with a nine year old boy and a pretty good script. But the film didn't end as it began, referring to the film's troubled production and the fact that it opened in theaters a week after 'Jurassic Park (1993). After the film's failure, McTiernan retreated to his home in Wyoming and took a break from his career.
The original screenplay was developed by Adam Leff and Zak Penn with Arnold Schwarzenegger in mind for the lead, and was titled "Extremely Violent". After Columbia purchased the script, the studio independently approached Arnold about the film. The star's decision came down to either the now-titled "Last Action Hero" or a Penny Marshall-directed Columbia comedy called "Sweet Tooth", with LAH winning out. The script was later rewritten by Shane Black and David Arnott to rev up the action sequences, and William Goldman did a $1 million polish when Arnold made it clear he would not begin filming until Goldman added depth for the film's characters.
In the film the characters are able to enter and leave the movie world via a magic ticket which is credited to famous stage illusionist and escapologist Harry Houdini. However in real life Houdini was firmly opposed to the idea of supernatural powers and spent his time debunking fake spiritualists and phony mediums.
Due to delays with the film Hook (1991), this was the first movie released in SDDS (Sony Dynamic Digital Sound). With five front channels and two rears, it was also the first film to include a 7.1 channel SDDS mix, rather than the more common 5.1 SDDS.
The fact that Jack Slater was out to avenge the death of his second cousin Frank in "Jack Slater IV" was an intentionally ridiculous element. The idea was that having gone through so many epic, personal conflicts with super-villains during the first three films, Jack Slater was left to battle the mob due to the death of a very minor character. This would also allow the Danny Madigan character to start listing the flaws of the Jack Slater films, as well as how they were running out of good ideas.
Before the Hamlet sequence, wherein the Laurence Olivier version is played on a projector, the teacher who introduces the film is Joan Plowright, an English actress and Laurence Olivier's third wife. Noting her students' apparent ignorance of Olivier's storied career, she tells them they may remember him as Zeus in Clash of the Titans (1981), one of Olivier's final roles.
Some trailers shows few deleted and alternate scenes, like extended Hamlet action scene where Arnold Schwarzenegger is in some water shooting at someone, Danny being blown away into the movie after dynamite pops out of screen, alternate take and angle for Slater's "I hate when that happens" line after he gets out of the tar pit. Couple other deleted scenes from original 140 minutes long rough cut include dialogue scene between Danny and Jack in which Danny says how his father died from cancer and scene where group of kids see Jack while he is walking across the streets in the rain with Danny looking for Benedict and they think he is Schwarzenegger so they ask him for his autograph which he signs.
The filming involved a 3:00 pm to 3:00 am, 7-day, shutdown of six-block Times Square area in New York City for the production. Originally, a giant 75-foot balloon of Arnold Schwarzenegger held three few sticks of dynamite in the balloon's hand but, following the then-recent 1993 bombing of the World Trade Center, Richard Brick, Commissioner of the New York City Mayor's Office of Film, Theatre and Broadcasting and Gary Martin, President of Production at Columbia Pictures agreed to change the prop to a badge.
While Danny is in the movie, he says John Practice (F. Murray Abraham) killed Mozart, a reference to the movie Amadeus (1984), where Abraham played Antonio Salieri. Later in the film, when Slater and Danny's mom are talking, the Overture to The Marriage of Figaro can be heard, composed by Wolfgang Amadeus Mozart.
In one scene Jack says to Danny, regarding his ex-wife, "Do you think I would marry someone so stupid that doesn't know the real voice from a taped one?" In Arnold Schwarzenegger's next film, True Lies (1994), he uses a taped voice to fool his wife.
These are the following guns in the movie. Slater: Desert Eagle .50 caliber Action Express; Benidict: Custom Dan Wesson Revolver .357 Magnum; Danny: SIG-Sauer P230; Vavoldi: Walther PPK custom engraved; Criminals: MP5K-PDW, M3A1 Grease Gun, and Intratec TEC-9 sub-machine guns; Slater/Hamlet:Switches from MAC-11 to MP5K; Van: Short Barreled Minigun. Whitney: Colt Python .357 Magnum; SWAT member: Colt Commando.
The real City Coat of Arms for Los Angeles has the American Federal Shield (with 13 white stars in the Chief) in the 1st Quarter, the California State "Bear Flag" (star in canton, a grizzly bear, and a strip in base; all in red) in the 2nd Quarter, the Mexican Eagle atop a green cactus (from the Mexican Flag) in the 3rd Quarter, and the parted arms of alliance for Castile and Leon (representing Spain) in the 4th Quarter. When Jack Slater pulls into the parking lot at "Police Headquarters" (actually a Sony Pictures office building), the Los Angeles Coat of Arms out front has the American Eagle (with a Federal Shield with 4 stars in the Chief in escutcheon) in the 3rd Quarter, and a Black Rhino (instead of the Red Bear) in the California State Flag in the 2nd Quarter.
