In the beginning of the film The Nines Ryan Reynolds' character gets out of the shower and freaks out because he does not have a belly button. This, of course, is later explained being that he's not actually human, but a God like entity that has created the entire world around him... However, there are several shots in the film where we can see he clearly has a belly button... Was this just something that was overlooked in production? Or, was it due to the crack he and the hooker had obtained earlier in the film? I know the movie has many different interpretations of various events throughout, I was just curious.
