Rian Johnson's original cut was "well over three hours long"

He said that the first cut was three hours long, but that was in his own opinion not the final cut. In the same interview he said that the eventual 150 minute cut is by far the best version of the movie and that he is not interested in a director's cut, since he considers the version to be shown in cinema's to be the director's cut. He did say that some of his favorite scenes had to be cut, because it didn't work with the rest of the movie. The deleted scenes will be released as extra's on the dvd release.
