Michael Imperioli by Eric Liebowitz/ABC

Casting/recasting news is beginning to trickle in as ABC tweaks its rumored-to-be- in-trouble just fine adaptation of the British series Life on Mars.

Jason O'Mara is still the lead - and dagnabit, he better remain the lead! - but now Michael Imperioli has joined the cast.

The Sopranos' former Christofuh! will fill the role of Det. Ray Carling, a colleague of Sam's who is mysteriously transplanted from the present into 1972.

Imperioli's lawman is described as a rule-bending tough guy who, when the chips are down, is handy to have in your corner. He was played by Dean Andrews in the BBC edition. - Matt Mitovich
