It's a suspenseful, well shot and an interesting yarn...except for one thing--it has the "you can't recognize Superman is Clark Kent because he isn't wearing glasses" silliness. A man is depending on a different identity based on the fact that he is wearing contact lenses (1949 contacts are frightening looking), You'd think he would have worn a wig or fake facial hair or something. The unbelievable premise makes the movie OK but not great.
