For those into Burn!, it will be playing at Film Forum in New York City at the end of September/beginning of October.

I would add to Joanna's recommendation of The Fugitive Kind, Brando in Reflections in a Golden Eye, One-Eyed Jacks (which he also directed replacing Stanley Kubrick) and Last Tango in Paris (which is basically Brando's greatest hits and some of the most honest and naked [both senses of the word] acting ever on screen).
