What I meant to say was Gene Hackman's Lex Luthor had a better evil scheme than Kevin Spacey's Lex Luthor IMHO...I know that Hackman's Luthor wasn't very menacing but what did you expect? Superman: The Movie was made in the 70's and nobody took comic book films seriously back then.
Everybody thought a comic book film was a joke and the directors treated every comic book film as a children's movie.
