BabeWatch... Gretchen Mol

"Life on Mars" returns to ABC tonight with a sweet new after "Lost." The show is about Sam Tyler, an NYPD cop stuck who is mysteriously trapped in 1973 Manhattan, where everything is slightly yellow -- exactly like you would see in a photograph taken in 1973. Watch "Life on Mars" for its loving production values, for Harvey Keitel, for Michael Imperioli's facial hair. Better yet, watch for the radiant Gretchen Mol, whose character needs much more to do.
