Once Upon a Time in America. the original release and the director cut are worlds apart.
Almost mentioned that movie also but only the US got the extremely shorter and edited 139 minute version of the film in Europe the movie was 229 minutes. The directors cut still has some scenes missing since when it first premiered it was 269 minutes. Also when they finished filming it they apparently had eight to ten hours worth of footage and the original plan was to release it in two parts that would have been three hours each.
