I am not a mathematician, therefore, thoroughly underqualified to judge mathematicians. However, I recommend George Andrews' lecture[1] on Ramanujan's relevance to current mathematics. I wish they'd make more movies about (other) mathematicians and scientists too, minus the fake drama like Ramanujan's physical abuse seen in this one.
