I don't know if this is good news or bad... David E. Kelley may be checking out of Life on Mars, the ABC pilot based on the hit BBC crime/time travel drama. According to Variety, the prolific Mr. Kelley -- Boston Legal, L.A. Law, Picket Fences, Ally MacBeal, The Practice, Chicago Hope, etc. -- is unhappy with the financial arrangements and if things aren't worked out, he's going to move on.

Life on Mars was a terrific show. The UK version has played on BBC America, starring John Simm and Philip Glenister. Following the British model, the series lasted just two years -- 16 episodes total. In the ABC pilot, which Thomas Schlamme directed, Jason O'Mara (Men in Trees) is playing Simm's role, Sam; Colm Meaney (Star Trek: The Next Generation) is Gene. Kelley wrote the American variation on the story of Sam Tyler, a police detective in present day who awakens from a car crash to find he's living in 1973. Has he really gone back in time or is it all in his head?

How's this for a fantastic premise: a driven and ambitious young British detective is determined to keep the streets of 21st Century Manchester safe. But after a near fatal car accident, he wakes up, dazed and confused, in 1973.

David Bowie's Life on Mars is playing on his iPod when he crashes, hence the title.

That's the background on a new series, Life on Mars, starting on BBC ONE in the U.K. on Monday 9 January, starring John Simm (24 Hour Party People) as Sam Tyler and Philip Glenister (Calendar Girls) as DCI Gene Hunt.

As you can imagine, poor Sam is like a fish out of water, with obscure moralities and strange views on the tough attitudes of tough-nut British detectives in the 1970s.

TV Squad will be watching the bizarre time-travelling cop drama, so expect some updates when the series kicks in.
