David E. Kelley is going back in time with a new drama project for ABC, which has received a put pilot commitment with a hefty penalty attached.

The show, targeted for fall 2007, is based on the BBC's 2006 sci-fi crime drama Life on Mars, which stars John Simm as a 21st century detective who, following a car crash, mysteriously finds himself working as a cop in the 1970s.

The Hollywood Reporter says Kelley is set to pen the pilot script and to executive produce the pilot.
