The Man Who Knew Infinity is pretty good, more accurate than some of the others on here. It focuses on Hardy (Jeremy Irons) and Ramanujan (Dev Patel). I'd recommend it to anyone looking for a good period drama with a good cast and nice sets. It's a very pleasant movie all around. It's not perfect but far better than others I've seen, like A Beautiful Mind, which I found painful to watch all those years ago.
