Over his more-then two decades at NBC, the onetime writer for The Simpsons honed a very specific and funny comedic persona.  Conan O'Brien Can't Stop is said to provide a a fascinating look at O'Brien with his guard down during the months after the whole NBC debacle.  This trailer allows us to get a good idea of that material, but also shows plenty of Conan being genuinely and characteristically funny.  Jack McBrayer, who plays Kenneth Parcell on 30 Rock, started out on Late Night, and he's seen briefly in the trailer being physically harassed by Conan.

Conan O'Brien Can't Stop will have a limited theatrical release on June 24th, along with subsequent VOD availability.

Here's the synopsis:

After a much-publicized departure from hosting NBC’s Tonight Show – and the severing of a 22-year relationship with the network – O’Brien hit the road with a 32-city music-and-comedy show to exercise his performing chops and exorcise a few demons. The “Legally Prohibited From Being Funny on Television Tour” was O’Brien’s answer to a contractual stipulation that banned his appearance on television, radio and the Internet for six months following his last show. Filmmaker Rodman Flender’s resulting 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 “half-assed show” (his words) is almost instantly assembled and mounted to an adoring fan base. At times angry, mostly hilarious, O’Brien works out his feelings about the very-public separation with comedy and rockabilly music, engaging in bits with on-stage guests such as Stephen Colbert, Jon Stewart and Jim Carrey, duetting with Jack White and sweating out manic Elvis Presley covers with his band and back-up singers. 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 (New York, Las Vegas) and remote (Enoch, Alberta) to fill a void within himself?
