He was in the movie The Fugitive and played the same character in US Marshals. From his biography looks like he has had a lot of guest appearance roles on lots of tv shows and was a regular for 3 years on Matlock.
Wonder how they are going to incorporate him into lost. Will he be in flashbacks that appear in 3 episodes or is he going to be one of those "we're not alone" people, like Ethan and that French lady. Can't wait for the reruns to be over (even though I still watch them

). Last weeks rerun there was a funny comment made by Hurley. It was the first time we see Hurley playing backgammon with Walt and of course Walt keeps winning and Hurley finally quits and Walt says "Hey you still owe me so & so dollars" (I can't remember the amount) and Hurley says "Don't worry you'll get it." It was really funny after seeing Hurley's backstory.
