I watched this film with no previous knowledge of its content or style and I was delighted to discover that it was a curiously interesting work. Very well acted by Jeffrey Hunter. A man who was often wasted in Hollywood. Surprised me the interplay Hunter has with Bernard Lee. It is quite mature and they play very well and with great sensitivity the part of father and son figures as the only survivors of a ship sinking. This was greatly helped by a very finely crafted dialogue. Instead, Michel Rennie and Wendy Hiller are quite stilted and their characters appear to be badly drawn and unidimensional. Today I saw this film with TWO endings. After the first ending a card appears on the screen telling the audience that this is an experiment. They'll show a second, different,ending and will distribute cards in he lobby of the cinema (I saw it on TV!) for a vote of which one was the favourite. Great!
