Muhammad Ali's Greatest Fight
You may not know this, but Muhammad Ali, possibly the greatest boxer of all time, wasn't allowed to fight for more than three years while in his prime. This resulted from his refusing to go to Vietnam and getting banned from boxing. He took his case to the Supreme Court and... well, if you know history, you know what happened. If you don't know history, you'll enjoy watching HBO's take on it. The cast features the likes of Frank Langella, Danny Glover, Barry Levinson, and Christopher Plummer.
