Thinking about this I just realized, that maybe the main protagonists were more likable to a French audience in the 1950s...? maybe it's just our modern sensibilities that take stronger objections at the über-macho, yet partly childish behavior. In which case, the first hour would have been more "entertaining" to those audiences and the 60min would have purely served as a drag, showing how desperate bored those men were. I'd buy that for a dollar
