Certifiably jonathan is a comockumentary directed by Jim Pasternak that weaves in and out of the bi-polar world of Jonathan Winters, where reality and fantasy collide. Jonathan Winters, an eighty years-old comic who served as the comedic mentor to scores of comedians including Robin Williams, Jimmy Kimmel and Sara Silverman (who all appear in the film) is also a gifted painter who dreams of having his work shown in the Museum of Modern Art. The filmmakers show his work to a famous art critic who believes Jonathan is “the missing link between Miro and Dali” and he convinces the museum to give Jonathan a show—but only if he paints three new paintings. Jonathan launches into a creative frenzy, but disaster strikes when his favorite painting is stolen along with his sense of humor. Without his humor, Jonathan can’t paint and is about to lose the opportunity of a lifetime. Jonathan sets out on a quest to get his mojo back, with the help of Sarah Silverman, Howie Mandel, Nora Dunn, Ryan Stiles, Tim Conway, Robert Klein, Kevin Dunn, Gary Owens, and the Arquettes.

Winter’s enduring notoriety with the boomers, and Betty-White-style popularity with a new generation of fans seems to have inspired broad interest in this off-kilter mockumentary which opens in theaters February 11th (the movie’s Facebook page already has 7,500 fans).
