He's not allowed to tell her about the plans for Japan, so she assumes the problem must be with him or her.
Not a war movie, but a movie about war, and in particular the 'war at home.' Eleamor Parker plays Tibbets' wife Lucy, who goes through hell in trying to hold her marriage together with a man who holds all sorts of secrets he's forbidden to share with her, almost to the point of divorcet. This film basically gave Americans an idea of what actually was going on before and during the decision to bomb Japan. Paul Tibbets, the pilot who flew the Enola Gay to drop the atomic bomb on Hiroshima. It's the true story (I'm sure Hollywood-ized as much as they could get away with) of Col. Above and Beyond is one of the better ones. Luckily he made some decent movies over the years - Waterloo Bridge, Rogue Cop, Camille, Johnny Eager. Robert Taylor is (was) so pretty, I'll watch anything he's in.
