(at around 1h 23 mins) G.W. Bailey had hoped to return as Lt. Harris, but was passed over in favor of Art Metrano as the antagonist in this film and Part 3. Bailey instead took a job working with director Hugh Wilson on Rustlers' Rhapsody (1985). On a day off, G.W. visited the Police Academy 2 set to film an uncredited cameo in the wedding reception scene. He appears from behind, as the man having his picture taken by the photographer.
Tim Kazurinsky was originally only to appear in the opening scene. But director Jerry Paris enjoyed the chemistry between Kazurinsky and Bobcat Goldthwait so the character of Sweetchuck was created during filming.
Despite the fact that no such character exists in the movie, a blonde policewoman appears on the official poster. This was an inside joke made by the producers, as they had also requested that the same "sexy girl" be included on an earlier version of the first film's poster.
The only movie in the original Police Academy heptalogy in which Callahan (Leslie Easterbrook) does not appear. After the first film was completed, Leslie was pregnant with a baby daughter, which prevented her from working on this sequel.
Tim Kazurinsky's character was to be called Mr. Schewchuk, as the name appears on the store window. Director Jerry Paris changed the name to Sweetchuck, after Bubba Smith flubbed several takes trying to pronounce 'Schewchuk'.
Upon being cast as seamstress Chloe Daniels, the love interest of Mahoney, Julie Brown had been told her role was that of a major ensemble player. Julie was later disappointed to learn that several of her scenes with Steve Guttenberg, bar two nearly cameo appearances, had been cut from the final print.
The only Police Academy movie to feature Commandant Eric Lassard's brother, Pete (Howard Hesseman). Howard was asked to reprise his role in later sequels, but he outright refused, saying that he regretted doing this film in the first place.
(at around 1h 6 mins) When Mahoney meets some of Zed's gang members while undercover, a Russian vulgarity is written among the graffiti on a phone booth. This was an inside joke, as producer Paul Maslansky is of Russian descent.
Though Proctor's first name is never mentioned in any of the Police Academy movies, it does appear in the script for this movie. The description of his first scene refers to him as Sergeant Carl Proctor.
Two of director Jerry Paris's children were cast in this movie. While his daughter Julie Paris was given a small role as the checkout girl Zed talks to, his son Andrew Paris played Bud, the punchy brother of Kathleen Kirkland.
Writer Barry W. Blaustein stated that he was approached during production by Bubba Smith (Hightower), who complained about being given a minimal amount of lines, compared to the other actors. The reason for this was that Blaustein had been told by producers that "Bubba couldn't do dialogue".
Michael Winslow (Jones), David Graf (Tackleberry) and George Gaynes (Cmdnt. Lassard) are the only actors who appeared in all 7 Police Academy movies. Winslow even goes a step beyond this, as he is the only actor to not only appear in all 7 Police Academy movies, but also had a regular role on Police Academy: The Series (1997).
Although everyone (even in subsequent Police Academy movies), refers to Tim Kazurinsky's character as "Sweetchuck", his name is actually "Schewchuk". This is evidenced on the sign outside his store. The name is a reference to the set decorator of the original Police Academy (1984) film, Steve Shewchuk.
(at around 37 mins) The service station attendant is reading a copy of 'The Wrestler' magazine. This was written into the scene by Barry W. Blaustein, himself a pro wrestling fan, who would go on in later years to direct Beyond the Mat (1999).
According to Paul Maslansky , the returning actors from the original Police Academy (1984) wanted more money to work on the sequel. The above-the-line (principal talent) costs were about one and a half million dollars, including Maslansky's own fee.
Steve Guttenberg almost did not return for the sequel, as he was not pleased with the script as originally presented to him. After some re-writes, and a bigger paycheck, Guttenberg was happy to reprise Mahoney once again.
In an interview prior to the start of production, David Graf said that he would not mind doing a series of Police Academy movies. "I'd do it strictly for the money. (Wife) Kathy and I went to a party at Hugh Wilson's and it was all very ritzy, with valet parking, caviar, champagne, all that. And while we were there, surrounded by all that luxury, Kathy and I were talking about how we were going to pay the gas bill. The gas company had told us they were going to discontinue service the next day. I don't want to be in that position again. So, yes, I would do a series of Police Academies - for money." True to his word, Graf went on to appear in all seven of the original Police Academy movies.
Shooting in Los Angeles was more expensive for this sequel than for the first film, according to producer Paul Maslansky. "Not because of the city officials; they provide every co-operation. It's the merchants and the property owners who can really hit you. There's so much filming going on that they ask a lot of money for location sites, parking, etc."
Lou the dog was played by a large Newfoundland dog called Kodiak. The dog was very stubborn, often dictating how many takes he wanted for a shoot. If he felt like he had had enough of a particular re-take, he would stop performing, to the letdown of his trainers Rob Bloch and Kim Lindemeon. However, he would later save the life of his owner Kathy Cullen, by alerting her to a dangerous fire that was burning in her home. Kodiak subsequently earned the Newfoundland club's prestigious "Versatility" award.
In an interview shortly after this film's release, Steve Guttenberg said that being in a major hit like Police Academy (1984), that earns a lot of money and extremely nasty reviews, is both a help and a hindrance. "There's an advantage because the film makes a lot of money. But the disadvantage is that they want you to keep doing it again and again. You can get stuck in them. I was very reluctant to do the sequel, but there's a contract. They've got options on me forever, but they're very understanding about my desires."
