Clark Gable shocked audiences with his bare, undershirt-free chest as he undressed for bed in this pre-Code classic, which also features the tearing down of a "wall of Jericho" between the beds of Gable and costar Claudette Colbert.
OK, so technically he's frozen, not asleep. But chaos ensues when Woody Allen "wakes up" 200 years later. Alas, he never runs into Sigourney Weaver's Ellen Ripley as she hypersleeps through time and space in the Alien series.
