'Act of Valor': 'Parenthood' Actor Walks Back Tweet Comparing Film to Nazi Propaganda

Actor Dax Shepard fired off a Tweet over the weekend comparing the new pro-military, pro-American film “Act of Valor” to “Triumph of the Will.’

Not familiar with that cinematic “classic?” Try this refresher course.

Now, the co-star of the NBC series “Parenthood” is trying to walk back his inflammatory post.

Shepard tries to tap Tweet his way out of it, but surely he knows the folly of making Nazi comparisons in modern society, let alone the power citizens have to call out actors on their 140-character musings.
