Trivia: The opening scene was supposed to be a reference to "Saturday Night Fever", but the production could not afford the proper soundtrack, and thus, Bill "strutting" down the street for a prolonged period now lacks any frame of reference.
Trivia: Netflix uses the International Theatrical Version of the film (which they tend to do a lot), that cuts a few jokes or changes some scenes from the US Theatrical Version. For example, instead of Tony Montana from "Scarface" in Ron's eyes, it's Frank Dux (Jean-Claude Van Damme) from "Bloodsport", which is also a mistake since the film came out in 1988.
Trivia: The director, Tommy Wirkola, has an uncredited cameo of sorts (seen on screen longer than a usual cameo) as one of Sheriff Berringer's four deputies. Stuntman Wolfgang Lindner portrayed one of the deputies, and is uncredited as well.
Trivia: In the batcave, the batmobile lifted by Bruce is the design from Tim Burton's Batman and Batman Returns films.
