Great movie. Based on a true story, the movie centers around a kindly, timid doctor, BRILLIANTLY played by the amazing Robin Williams. For anyone who thinks he can't tone down his maniacal energy, think again and watch him in this. His character finds an experimental drug that wakes comatose people up. Great acting by all. Robert DeNiro us cast against type and great. A little dramatic of a movie, but probably on purpose. I cry every time I see it. Highly recommended.
