Celtic thesp Jason O'Mara, who had the lead in ABC's new take on investigator Philip Marlowe (but, alas, that pilot was not picked up), is still set to do some sleuthing, only this time in the '70s. According to the Reporter, O'Mara has been tapped to front Life on Mars, David E. Kelley's BBC-series-inspired ABC pilot about a detective mysteriously transported three decades into the past after his girlfriend is kidnapped.

O'Mara's role was deemed so tricky to cast that Life was suspended from this past development cycle, and now hopes for a mid-season bid. What About Brian's Rachelle Lefevre has the female lead, playing the rare lady detective during the disco days.

O'Mara's recent creds include Men in Trees and In Justice.
