When the filmmakers asked Adrienne King to reprise her role as Alice, she said that she wanted to be on screen for a short period of time because there was an obsessive fan who was stalking her, broke into her apartment, and she feared for her life.
Following the release of Friday the 13th (1980), Adrienne King had numerous encounters with an obsessive fan. The situation escalated into a stalker case, and she decided to avoid any further acting opportunities. She has not done any on-screen film work since, but has done voice over work on several films more than 15 years later.
Originally, sex scene between Sandra and Jeff was longer and it included full frontal nudity from actress Marta Kober, but when Paramount studio discovered that she was underage, the scene was deleted completely.
Jason in this film is dressed to look exactly the same as the hooded, burlap sack killer from The Town That Dreaded Sundown (1976). The only difference is that the burlap sack he wears has only one eye hole, and his shirt has a slightly different plaid design.
The first Jason scene in the movie is a shot of Jason's legs walking across the street toward Alice's house. This is the only time in the series Jason was played by a woman. Jason's legs belonged to Ellen Lutter, the film's costume designer.
The counterintuitive plot of part 2 shocked most people associated with the series. Betsy Palmer, Tom Savini and Sean Cunningham all have made public remarks about how stupid it was that Jason was alive the whole time, and if he was then why didn't he just tell Pam Vorhees that he was alive which would have avoided all the murders in part 1.
Amy Steel has stated that she found shooting the "window scene" difficult. The shot required three takes and her frightened reaction is genuine. Because the shot was in slow-motion, a high-speed camera was used, and every time she heard the film start running, she would tense up and get scared.
With Tom Savini unavailable, they turned to Stan Winston deliver the gore for Part 2. Unfortunately, Winston was forced to leave due to scheduling conflicts, making way for Carl Fullerton. Within 5 years, Winston won an Oscar for his work on James Cameron's Aliens, and his Stan Winston Studios would go on to be responsible for the design work on The Terminator, Alien, Jurassic Park, and Predator series. After a decade in gore, Fullerton ascended to the A-List of Hollywood make-up artists with Glory, The Godfather Part III, Silence of the Lambs, and Philadelphia.
Although Warrington Gillette is credited as playing Jason, in most of the scenes the character was played by stuntman Steve Dash. Gillette only plays the unmasked Jason in the sequence where he bursts through a window. Dash was upset at being uncredited in the role, as he has most of Jason's screen time. When archival footage from this film was used in the next sequel, only Dash is credited as playing Jason.
During the scene where Jason is chasing Ginny and she jumps out of the woods. Steve Daskawicz ended up falling on the pickax and breaking his ribs. Another time he was knocked out, and another time Amy Steel actually cut his finger while shooting the ending scene where she fights him with the machete. He ended up going to the hospital, getting stitches, and returning to work.
At a horror convention in Cherry Hill, New Jersey in 2003, Betsy Palmer said she never appeared in another Friday the 13th movie after the first one. Apparently she forgot about this one. Palmer was in Los Angeles at the time Part 2 was filming in Connecticut. She was hired for one day, filmed in front of a black screen.
In the scene when Jason crashes into the window and grabs Ginny, the actor, Warrington Gillette was actually hurt. He tried to break into the window, only it didn't break, and he ended up banging his head really hard on the glass.
In a break between takes, the cast and crew were highly amused when two girls attempted to use the telephone in the phone box which Jeff and Sandra use in the film. The telephone was, in fact, fake, and the girls soon stormed off in anger, assuming that the phone was not working.
Betsy Palmer was very surprised to be asked back for a cameo appearance by director Steve Miner, as she assumed that Jason was dead. She filmed her lines in half a day, and a new mockup of her head was created by the make-up effects team. She claimed that she had never seen the final film itself.
Warrington Gillette's agent told him he had a part for a Camp Counselor for him (Paul), and he auditioned but didn't get the part. However, they liked him, and knew he had gone to stunt school, so they asked him to be Jason.
The film takes place five years after the first, which was set in 1979 according to Friday the 13th: The Final Chapter (1984). Meaning that this film takes place in 1984. During both summers, both the Friday the 13th's occurred in July making this film take place exactly five years after the events of the first film.
Director Sean Cunningham and writer Victor Miller just made Friday the 13th to rip-off Halloween, but even they drew the line at doing a sequel centered around Jason. Legendary make-up/practical effects wizard Tom Savini, who made his name with Friday the 13th, agreed, "So, is [Jason] living off crayfish by the pond for 35 years, and nobody saw this weird kid?" Friday the 13th producer Steve Miner, on the other hand, had no such professional reservations. Cunningham, Miller, and Savini walked, leaving then 29-year-old Miner to take over as director. Ron Kurz, who performed un-credited re-writes on Miller's Friday the 13th script, took over scripting duties. Cunningham did eventually return to assist good friend Miner with casting and pre-production.
According to co-producer Dennis Stuart Murphy, the idea to have Jason wear a pillow case over his head in Part 2 came from their costume designer, who figured it was the type of readily available item Jason could have conceivably and easily procured
Despite the well known slasher pop culture concept of Jason Voorhees primarily murdering teenage and young adult Camp Counsellors at Camp Crystal Lake this marks the first of only two Friday The 13th film installments where Jason actually does such, the other being Friday the 13th Part VI: Jason Lives (1986).
In a deleted part of the ending: After the camera has completely zoomed in on Mrs. Voorhees' head, her eyes open and she smiles at us, indicating that Jason has killed Paul. This was cut for looking too fake. Since it was cut, it is now not considered evidence that Paul was murdered.
Actress Adrienne King (who played Alice) explained how her death (the ice pick scene) was filmed on Facebook: "It was a "retractable" ice pick that was not tested before use...the first time the ice pick did NOT retract. Second take..the lazy propsman (not Jason) had to aim for the hole in my face!"
It is believed that had Paramount not agreed to finance this film and the following sequels, Warner Bros., who distributed the first film outside the US with great success, were willing to step in and take over.
Adrienne King revealed in an interview to Screenrant that she didn't know that Alice was going to die until she arrived on the set she stated: "I actually said to them that I would do whatever they needed for the sequel, I was theirs. And I was very happy -- and I never got a script. Didn't even get a script. Then there was a car that picked me up, and little did I know, but I get up there and the crew's almost gone. Everybody had gone. I didn't realize, but they had actually filmed the movie already".
Warrington Gillette, who originally auditioned for the role of the head camp counselor Paul, was cast as Jason. However, he could not perform his own stunts. They brought in stuntman Steve Daskawisz (aka Steve Dash) to play Jason. Gillette ended up being credited for the role, but other than the final scene where an unmasked Jason breaks through a window the guy underneath that pillow case was usually Daskawisz.
On the back of the Deluxe Edition DVD, there is an image of Paul that is not seen in the film. He has his head wound from the film and he has a dead look in his eyes. This is a photo of John Furey, the actor portraying Paul, just goofing off between shots and it is a mystery how it ended up on the DVD, but it could be a vital clue as to what Paul's fate might have been (although he is not seen in the shack in the closing shot among the other bodies.
This came out the same year as Halloween 2. (John Carpenter was basically coerced into creating another Halloween movie by the studio after the runaway success of Friday the 13th). But whereas Halloween 2 is generally considered a step down from the original, Friday the 13th Part 2 is generally considered by series fans as being better than Part 1. With a stronger villain, Jason, who is creepy and menacing here without becoming superhuman and ridiculous as he did the in later entries in the series, and featuring crisp and effective direction by Steve Miner and many startling set pieces, it's actually considered to be the best in the series.
Friday the 13th's production crew gained a notable new addition for Part 2 in the form of Frank Mancuso, Jr., a recent college graduate at the time who happened to be the son of the President of Paramount Pictures. Mancuso, Jr. worked on Part 2 as an associate producer/roving crew member. By Part 3, he became the steward of the Friday the 13th series, producing the next batch of sequels, and executive producing the Friday the 13th TV series.
The trivia items below may give away important plot points.
According to Adrienne King, there was no script for her scene which is why she didn't know her character died. She showed up to set, found out Jason was going to kill her, and that they needed her to completely improvise a phone conversation. So, everything with Alice talking to her mom on the phone about struggling to move on with her soon-to-end life was unscripted.
Throughout the final scene, the mummified head of Mrs. Voorhees is noticeably an actress wearing makeup rather than a fake head. The final shot is a close-up of the head, ending in a freeze frame before the credits roll. Originally this shot ended with Mrs. Voorhees opening her eyes and smiling, but at the last minute Steve Miner decided this effect was hokey and cheapened the movie's impact.
During the climactic fight between Jason and Ginny, Jason raises the mattock to block Ginny's machete swing. Amy Steel said that during the first take, the timing was wrong and she accidentally hit Steve Dash's finger, causing him to have to go to the emergency room. Steve Dash has photos of him being treated in the ER in full costume, fake machete still stuck through his shoulder. After his finger was stitched up, he returned to set that night and insisted they complete the scene. She said they simply put a rubber cot on his finger, and applied make-up to make it look dirty.
One of the biggest mysteries of the "Friday the 13th" series is if Jason Voorhees didn't drown in the first movie and actually hid in the forest, or if he did and he rose from the dead to avenge the deaths of his mother and himself.
(at around 1h 3 mins) Immediately after Jeff and Sandra are killed, Jenny and Paul leave the bar and are passed by a man in a raincoat entering the bar. That was Bill Randolph, the actor portraying Jeff. He convinced director Steve Miner to let him do a run-through in the scene since no one would think of him since his character had just been killed on-screen.
Body Count: 9. (Plus one character presumed dead, but it's unconfirmed. If you count the bodies from the dream sequence recapping the end of the first one, you can add three more to the total body count.)
Inside Jason's cabin, in addition to the severed head and clothing of Pamela Voorhees, there are 3 bodies on the floor: Terry, the Sheriff, and the decomposing corpse of Alice. You can clearly see the icepick still sticking out of her head, but she is otherwise unrecognizable, as even the clothes have rotted. Oddly, Pamela, who has been dead two months longer than Alice, has faced less decomposition and her clothing merely looks worn and dirty.
The popular horror slasher sub-genre trope of skinny dipping always resulting in death began with this film, as Kirsten Baker's teenage Packanack Lodge counsellor character Terry does such in Crystal Lake before her and Russell Todd's teenage counsellor character Scott are murdered by Jason Voorhees.
Even though he plays Jason unmasked during the dream sequence, Warrington Gilette is the shortest of the actors who have played Jason at 6'1, where as the other stuntmen who portrayed him were 6'2 - 6'5.
