The fact that Charlie Kaufman is making a new film is, in and of itself, incredibly enticing. The fact that Kafuman’s new film will focus on the back-and-forth between an online movie blogger and a filmmaker ups the interest level even more. Now Kevin Kline has joined the cast of Frank or Francis and will be playing two supporting roles, bringing my excitement level into the “dangerous to your health” category. Variety reports that Kline has joined the Hollywood satire that features Jack Black, Steve Carell, and Nicolas Cage. Black plays an Internet troll who writes movie reviews for a living, while Carell is playing a somewhat pretentious filmmaker who happens to be cheating on his wife. As for Cage? He’s playing a character called The Emcee, an actor famous for big-budget commercial fare whose last hit was the movie Fat Dad. Obviously.Hit the jump for more, including details on Kline's incredibly strange roles.According to the report, Kline will be playing a character named Richard, the brother of a director whose calling card is Hiroshima, the highest grossing film of all time. Additionally, Kline will be playing Richard’s Head, which is an animatronic head that helps Richard’s brother “develop a completely inoffensive product that will have the broadest possible appeal and zero artistic integrity.” So, yeah. Never doubt Kaufman’s knack for the unique.As previously reported, Frank or Francis will also be a bit of a musical. Kaufman stated that it’s not a musical of the conventional sort, but it has about 50 songs in it. Kaufman is, of course, responsible for writing such fantastic fare as Eternal Sunshine of the Spotless Mind and Adaptation. He made his directorial debut in 2008 with Synecdoce, New York. Production on Frank or Francis is schedule to begin in January.
