Retroactively done with Will Ferrell and his character's name, Marshal Willenholly. Guess who plays Marshall in the 2009 Land of the Lost big-screen adaptation.
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.
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.
The Russian website kino-govno.com borrows its name from the Russian Woolseyism-laden translation's rendition of Moviepoopshoot.com (the title literally means "film-shit.com"). The site's creators are self-confessed huge fans of Kevin Smith.
Doing It For The Fans: Kevin Smith has gone on record saying the movie is a love letter to the fans after all the years of support for his work, which is why he tried to work in as many references to all previous films he could and centered the entire movie around Jay and Silent Bob in the first place.
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.
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.
