Sorry to tell you this guys, but when I originally saw the documentary that came with the DVD for The Richard Donner Cut
, it was Donner who wanted his creative consultant Tom Mankiewicz to decide whether to go with "the kiss ending" where Lois forgets everything or to turn back time as in Superman: The Movie
Tom Mankiewicz decided to go with the turn back the time ending (again), because in his opinion to Donner, it is Superman who should be kissing Lois at the end and not Clark Kent. So, that is why we endedup with the turn the time ending for The Donner Cut
, thus messing up the entire narrative of said film in the process.
