Kaufman begins casting his musical indie.

Steve Carell, Jack Black and Nicolas Cage have joined the cast of Charlie Kaufman‘s long-gestating musical indie ‘Frank Or Francis,’ reports Variety.

While plot details are being kept under wraps, it is known that the movie chronicles a volatile back and forth between a film director (Frank) and an online blogger (Francis), who takes delight in berating his cinematic talent.

Kaufman is trying to lock down two major female roles, both of which require singing. Talking at the Goteborg International Film Festival earlier this year, Kaufman said, “it is a musical. But it’s not a conventional musical. But it does have a lot of singing in it. There are 50 songs in it.”

Production on ‘Frank Or Francis’ is expected to being early 2012.
