The one that has had the biggest success is definitely Michael Emerson in Person of Interest. He is f*cking awesome in the series. Daniel Dae Kim has had a nice run on Hawaii Five-O, which has seen a few guest stars with recurring roles on it such as Jorge Garcia (Hurley), and Terry O'Quinn (John Locke). But Emerson is definitely on the upswing of former cast-mates of Lost. Ken Leung (Miles) has appeared on Person of Interest a couple of times and Elizabeth Mitchell (Juliet) did her best to save Revolution.

That's good to hear.  Those folks did some fine acting.

What about Matthew Fox (Jack), Evangeline Lilly (Kate) and Josh Holloway (Sawyer). They all had dominating roles. They didn't just fade away did they?
