1 of 16Jason O'Mara, Terra Nova
O'Mara proved he could play a time-travelling cop on ABC's short-lived Life on Mars, but what really works for him in Fox's dino drama is his balance of stoic strength and a sense of humor. (He ain't so bad to look at either!) O'Mara is relatable and grounds the story in reality — or at least as much reality as a show that features time warps and dinosaurs can hope for.
