Lillinds from the Icanspeel Forum compiled a list of movie terms along with their definitions. Below are a few examples:

DC (Director’s Cut):
A director’s cut is a specially edited version of a movie that is supposed to represent the director’s own approved edit of the movie. It is often released some time after the original release of the film, where the original release was released in a version different from the director’s approved edit.

LiMiTED:
A movie is LiMiTED when it has a limited theater run (in less than 300 UK theaters, or in less than 500 USA theaters). Mostly smaller films (such as art house films) are released as limited.
