Rodman Flender's documentary Conan O'Brien Can't Stop offers an intimate portrait of an improvisational artist at the most improvisational time of his career. Of course we're talking about the former Tonight Show host Conan O'Brien, essentially forced out of his job by NBC. Following that much-publicized departure in 2009, and well before he launched Conan on TBS late last year, O'Brien hit the road for a 32-city music-and-comedy show. The film presents some of the onstage banter from the tour, plus bits from guests including fellow TV comedy show hosts Stephen Colbert and Jon Stewart, plus actor Jim Carrey and rocker Jack White.
