Did any of the stars of the show go on to do other good stuff. I don't recall seeing any of them anywhere.

Then again, there's a huge swatch of TV I don't give light of day, let alone news about.

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.
