Steven Spielberg and Diablo Cody to re-team on an untitled comedy.

Diablo Cody, the Oscar-winning ‘Juno’ scribe has been tapped to pen an untitled comedy script – based on an original idea by Steven Spielberg.

Details of the project are being kept tightly under wraps (even dealmakers involved with the project were in the dark). So far, there are no producers yet attached.

The project marks the second time the pair have collaborated. Cody wrote the pilot and is exec producing Showtime series ‘The United States of Tara,’ also based on an original idea from Spielberg.

Cody first came to the attention of Spielberg when Mandate Pictures was looking for a distributor for ‘Juno,’ well before Jason Reitman was attached as the film’s director. Spielberg even considered directing the teen pregnancy comedy at one point.

Cody is currently working on ‘Tara,’ which stars Toni Collette and John Corbett.
