Superman: The Movie, The Donner Cut

We talk about the first 2 Superman movies (1978 and 1980), and in
particular the craziness that was going on behind the scenes with
Alexander and Ilya Salkind and Richard Donner, just to get these
movies made! What was the original story arc supposed to look
like? Why is it that when you watch the Donner cuts of Superman I
and II they essentially have the same ending, with Superman
turning the earth backward? We explain all this and more,
including the cutthroat methods of the Salkinds, the removal of
Richard Donner as director before Superman II and the subsequent
rewrites and reshoots of much of his work on Superman II, the
addition of Richard Lester, and the eventual creation of the
Donner Cut of each film.
