Winslet & Keener Join Kaufman's Frank or Francis

Kate Winslet and Catherine Keener have come aboard Charlie Kaufman's musical/comedy "Frank or Francis" says Vulture.

The story centers around an online war that develops between a successful filmmaker (Steve Carell) and a movie blogger (Jack Black). Nicolas Cage also stars as The Emcee, an actor known for commercial successes such as Fat Dad, and Kevin Kline stars as the director's brother.

 No details were were offered about Winslet and Keener's characters.

Kaufman will direct his own screenplay.

Anthony Bregman is producing the satire.

Both ladies have worked with Kaufman before; Winslet earned an Oscar nomination for her performance in 2004's "Eternal Sunshine of the Spotless Mind," while Keener got an Academy nod for her part in 1999's "Being John Malkovich."

Production is expected to begin later this year for a 2013 release.
