The movie has some really great bits, from the creation of the XF-11 to the Senate War Committee hearings between Hughes and Senator Brewster. It's motivated me to learn a lot about Howard Hughes the man, reading mostly articles on wikipedia. He's an example of a man who wanted great things for the world and went out and got them, and everything in biographies I can find makes the movie seem relatively accurate to the story. It's up for a lot of awards, and I hope it wins them.
After hearing a recent NPR piece on Mirimax, I'm sad to think this might be one of the last movies that is put out by the original creators of the company, but at least it was a great one.
