Didn't Taylor and Lucas disagree over how the movie should be shot?
Ahhh, the days before the Yes Men.
Forgot that he shot Dr. Strangelove (which featured James Earl Jones as one of the bomber pilots). Never considered the parallels between the war room and the Death Star interiors.
A big reason Lucas hired him was because of his work on The Dam Busters, the climactic sequence of which George modeled the trench run after.
