After a much-publicized departure from hosting NBC’s Tonight Show, O'Brien hit the road with a 32-city music-and-comedy show to exercise his performing chops and exorcise a few demons. Filmmaker Rodman Flender's documentary, Conan O'Brien Can't Stop, is an intimate portrait of an artist trained in improvisation, captured at the most improvisational time of his career. It offers a window into the private writers room and rehearsal halls as O'Brien's "Legally Prohibited From Being Funny on Television Tour" is almost instantly assembled and mounted to an adoring fan base. At times angry, mostly hilarious, we see a comic who does not stop — performing, singing, pushing his staff and himself. Did Conan O'Brien hit the road to give something back to his loyal fans, or did he travel across the continent, stopping at cities large and remote to fill a void within himself?
