Actors: Biff McGuire, Faye Dunaway, Jack Weston, Paul Burke, Steve McQueen. Why does he do it?. Naturally, these two will get it on, because they have a lot in common: they're not people, they're walking clothes racks.
In my humble opinion, not as dynamic as the remake. But it gives a solid foundation for understanding the main characters. Great as an insight to the era.
