I first heard of John Waynes draft dodgin antics when i was a kid in the late fifties, early sixties when WWII vets would cuss him when someone would bring up one of his movies. Later in life i remembered those times and began looking into it. The WWII vets were right.

Others like Clarke Gable, Jimmy Stewart, and others put their careers on hold, and went to war, but not ole John. He was busy beddin Marlene Dietrich while still married to his 1st wife.
Tommy Lee Jones is another actor that plays the patriotic movie parts. Really great in westerns, but in reality a raging liberal who campaigned for AL Gore.
There's what they portray, and then there's the truth.
