- Acting for Two:
- Actor-Inspired Element
- When Justice asks Jay what "snoogans" means, he says it means, "I'm kidding." This is true: Jay's odd catchphrases evolved from random vocalizations Jason Mewes would make as a teenager whenever he'd jokingly say something nasty (e.g., "I just fucked your mom! Nooch!").
- Shannon Elizabeth added the idea of Justice being nearsighted. Why? Because "Justice is blind."
- Tracy Morgan's drug dealer character was originally unnamed. Morgan came up with the character's name - Pumpkin Escobar - the day they filmed the scene. Morgan also came up with the idea of Escobar's sidekick Scott, reasoning that if his character was the West Coast Jay, he should have a West Coast Silent Bob.
- Billing Displacement: Jason Mewes is billed fifth on the poster and Kevin Smith isn't billed at all, despite the fact that they are the stars of the movie.
- In fairness the six names on the poster are in alphabetical order by last name, and Smith would be the seventh. Also, as he is the writer/director, (a) his name is on the poster in that regard, (b) it could be modesty, and (c) it might be the joke—that Jay and Silent Bob's actors can't even get top billing in their own movie. Also, he may be one of the two title characters, but he has the fewest speaking lines of the seven.
- Completely Different Title: In Brazil the movie received the title O Império (do Besteirol) Contra-Ataca (Something like The Empire (of Nonsense) Strikes Back).
- Defictionalization: Moviepoopshoot.com was live for a while, and posted new content after the movie's run. It was later Quick Stop Entertainment, tying in with the c-store of the narrative of the saga (it's now called Fred Entertainment and is owned by Ken Plume, editor in chief of the former Quick Stop Entertainment). Brodie's comic shop is actually Kevin Smith's, in Red Bank, New Jersey.
- Mutually Fictional: The duo stumbles upon the the filming of a Scream movie. The first movie in the series had a poster for Clerks, a movie in the same continuity as Jay and Silent Bob. And yet, Jay and Silent Bob had appeared in Scream 3 as themselves taking a tour of the Show Within a Show Slash.
- Subtler is Matt Damon referencing Dogma as a film that he and Ben Affleck were in, even though the events of that film happened to characters within this one.
- I Want You to Meet an Old Friend of Mine: Averted. While Mark Hamill and Carrie Fisher make cameo appearances, they don't share any scenes together. In fact, neither of them realised the other was in it.
- Production Posse: Since this was going to be the last View Askewniverse film, Kevin Smith got pretty much everyone who had even a minor role in the previous films to come back and at least make a cameo.
- Well... Except for Linda Fiorentino.
- Prop Recycling: Chris Rock's image on the poster is recycled from Dogma, oddly- you can tell because he's wearing Rufus' outfit (as opposed to Chaka's).
- Quote Source: For The Internet.
- Real-Life Relative: Baby Silent Bob was played by Kevin Smith's daughter Harley Quinn Smith. His wife Jennifer Schwalbach Smith played Missy.
- Recycled Script: About half the film- mainly the spoof of The Fugitive- was recycled from a comic book Smith made called Chasing Dogma, which attempted to fill the gap in between the two movies.
- Refitted for Sequel: Jay's line, "What's with the knife, are we having cake or something?" was meant for the train scene in Dogma.
- Those Two Actors: Lampshaded with Ben Affleck and Matt Damon.Matt: Let's remember who talked who into doing this shit in the first place. Talking me into Dogma was one thing, but this...
Ben: Hey look, I'm sorry I dragged you away from whatever-gay-serial-killers-who-ride-horses-and-like-to-play-golf-touchy-feely-picture you're supposed to be doing this week.
Matt: I take it you haven't seen Forces of Nature?
Ben: You're like a child. What've I been telling you? You gotta do the safe picture. Then you can do the art picture. But then sometimes you gotta do the payback picture because your friend says you owe him.
Ben: And sometimes, you have to go back to the well.
Matt: And sometimes, you do Reindeer Games.
Ben: See, that's just mean.
- Throw It In!:
- "Hey kids! It's Mark Hamill! (Applause)" No really, test audiences had no idea who he was under all of the costuming, as well as the fact that he hadn't been in a live-action movie in years.
- Jay stopping the fight with the Cock-Knocker to take a hit on his bongsaber was an idea Jason Mewes came up with during rehearsal.
- Holden's summarization of Silent Bob's feelings towards Jay were improvised by Ben Affleck on-set. Silent Bob's nodding was Kevin Smith's genuine reaction, and approval for a possible thought tracking for Bob from Ben.
- According to Smith's commentary, there was no prompting to make the orangutan swing in Jay and Silent Bob's hands to grip the railing with its feet when the trio were accosted by the police outside the diner. That was just the orangutan being an orangutan.
- Troubled Production: On his podcast Jay and Silent Bob Get Old, Kevin Smith went on at length about how much of a headache this movie was, mostly owing to Jason Mewes' alcoholism and other drug abuse turning him into a "ticking time bomb" which threatened to shut the project down at any moment. During pre-production, Mewes would have constant mood swings due to heroin withdrawal, to the point that Smith actually threw him out of his car on their way to the set one day. Mewes would drink heavily after every day of shooting, compensating for his lack of other drugs, and nearly got into a fist fight with Scott Mosier when he had to come back one night for a reshoot while drunk (Mewes later said that he was too intoxicated to remember anything that happened during production). When the shoot wrapped, Smith told Mewes point-blank to get sober or he'd never speak to him again. This is partially why he eventually decided to do Jay and Silent Bob Reboot, because he wanted to have better memories working with Mewes than he did on this film.
- Unintentional Period Piece: The film references works from multiple decades, though the early to late 90's are treated as being recent, with movies from the year 2000 being the most topical. The ''Daredevil Early-Bird Cameo references a movie that had not yet been released at that time.
- Also, Jay not knowing about the existence of the Internet was at the cusp of pushing believability in 2001.
- What Could Have Been
- Kevin Smith had originally pegged Howard Shore, composer for his previous film, to do the score for this film, but Shore got caught up in the The Lord of the Rings. Then Smith remembered how much he enjoyed working with James L. Venable on Clerks: The Animated Series and thought "Well, this is basically a live-action cartoon..."
- The original plot involved Jay and Silent Bob trying to save their beloved Quick Stop.
- Justice's introduction was originally going to be scored to the Prince song "The Most Beautiful Girl In The World," but the Purple One refused to license it (though he still gave permission to use Morris Day and The Time's "Jungle Love"). Smith approaching Prince for the rights led to him getting hired for the notorious unfinished documentary described in An Evening with Kevin Smith.
- Heather Graham was originally offered the role of Justice, but turned it down, because she couldn't figure out why her character would fall in love with Jay. Selma Blair was also considered.
- At one point, Seth Green was considered to play "Jay" in the Bluntman and Chronic movie. This is an inside joke. Gramercy Pictures didn't want Jason Mewes to reprise his role as Jay in Mallrats, and, up until the first day of shooting, tried to replace him with Green.
- Charlie Sheen was reportedly offered the role of Marshal Willenholly, but he turned it down because he couldn't get a grasp on the character.
- David Duchovny originally called Smith, and told him that he wanted the role of "Cocknocker". Smith gave him the role, but unfortunately when it was time to start shooting, Duchovny was already filming Evolution, and could not make it. Mark Hamill was then brought in as his replacement.
- Salma Hayek was originally going to reprise her role as Serendipity the muse from Dogma, working on the Miramax lot. However due to scheduling conflicts she had to drop out. There is a painting of her at the start of the Scream 3 spoof instead.
- Smith originally wanted Matthew Lillard and Freddie Prinze Jr.. to be the stars of the fictitious Bluntman and Chronic movie, because, at that point, they had starred in several Miramax films together. They passed on the project, choosing to do Scooby-Doo instead.
- In the original script, Quentin Tarantino was the director of Bluntman and Chronic. This draft also featured a cameo from Harvey Weinstein (which thankfully in hindsight didn't happen).
- There was brief consideration early on in production of making an actual Bluntman and Chronic film.
- In earlier drafts Ben Affleck and Matt Damon were central characters and even set the plot off.
