The tinkering over at ABC's port of the Brit hit Life on Mars continues.

Recently, it was announced that The Sopranos' Michael Imperioli was coming on board as a trustworthy colleague of Jason O'Mara's transplanted-in-time lawman. Now, I have learned exclusively, the trio of exec producers (Josh Applebaum, Andre Nemec and Scott Rosenberg) who claimed the Life on Mars reins from David E. Kelley - and each of whom hail from October Road - have tapped a cast member of that ABC serial to join their new venture.

Jonathan Murphy, aka OR's Ronnie, will play Detective Chris Skelton, a jittery young arrival to the department. (The role was filled by Marshall Lancaster on the BBC original.)

Thus far, the female lead for ABC's Life on Mars has yet to be cast. - Matt Mitovich
