I liked this movie a lot. I'm not a huge fan of biographical epics, but I guess when you throw enough directorial talent, acting talent, sharp screenwriting, and special effects up on the screen, you're going to get something watchable. And this long movie just flew by (heh).
No surprise that this movie was nominated for 11 Oscars, and won 5. Cate Blanchett won for her portrayal of Katherine Hepburn, richly deserved.
The movie's unexpectedly funny in spots; don't know if Howard Hughes had much of a sense of humor in reality, but the folks who made the movie definitely did.
