MICHAEL EMERSON, 57: Lost's Emmy-winning Emerson plays a man of mystery in CBS' new Person of Interest, teaming up with a former special forces guy (Jim Caviezel) to stop crimes before they happen. In the J.J. Abrams-produced series, Emerson's computer genius billionaire character has figured out how to tell when people are planning very bad things. Thanks to omnipresent traffic cameras, cellphones and myriad other monitoring devices of today, he and his partner can also tell where people are at a given time. It's Big Brother stuff, for real.
STEPHEN LANG, 59: The actor-playwright, who counts Stonewall Jackson in Gods and Generals, George Pickett in Gettysburg and Col. Quartich in Avatar among his many roles, now tries out his leadership abilities as head of the time traveler colony on Steven Spielberg's dinosaur show Terra Nova, a big Fox gamble. He calls his new character, Commander Nathaniel Taylor, an idealist with a heroic quality. Looks like he'll need it.
