Other mistake: When Otto Preminger calls Trumbo from his car to announce that Trumbo's real name would be credited for Exodus, Preminger tells him to look at the front page of the New York Times. The problem is that Trumbo has already picked up the paper from his counter and is reading before Preminger even tells him which newspaper features the article.

You must fight for his right to speak and be heard. All civil liberties go hand in hand. And when one goes, the others are weakened. Just as a collapse of one pillar in a house would endanger the whole structure.
