I just found out about this and it's something I guess I should have known about before.

Alan Smithee (also Allen Smithee) is an official pseudonym used by film directors who wish to disown a project. Coined in 1968 and used until it was formally discontinued in 2000,[1] it was the sole pseudonym used by members of the Directors Guild of America (DGA) when a director, dissatisfied with the final product, proved to the satisfaction of a guild panel that he or she had not been able to exercise creative control over a film. The director was also required by guild rules not to discuss the circumstances leading to the movie or even to acknowledge being the project's director.
