TJ Jagodowski and David Pasquesi are two of the world's finest improvisers. Their two man show "TJ and Dave" has a cult following at the iO in Chicago and at the Barrow Street Theater in New York. This documentary captures one of their New York shows, bookended with their thoughts on the process of improv and their partnership together.
This is the best documentary I've ever seen about improvisation and their performance is really phenomenal. If you have Netflix, you can stream it on demand. I really can't recommend it enough.

And here's a link to an audio interview I did with them before one of their shows last summer: http://hostandguest.blogspot.com/200...-and-dave.html
