Answer: There have been several conflicting reasons given as to why this movie is called "Movie 43." Some people claim it's a reference to "rule 43 of the internet." (Although there are also several different conflicting versions of the 43rd rule of the internet, so this explanation is pretty shaky.) Some claim it's an inside joke between the main producer and his kids about a fictional "banned film" they heard about called "Movie 43" that didn't really exist. And some people claim it's just a random title they attached to the film with no actual meaning.
