I was a big fan of the pre Star Wars Mark Hamill. From the short lived sitcom "The Texas Wheelers"

I remember him from a Kodak commercial. A two part episode of "Owen Marshall Counselor-at-Law", and an episode of "The Magician" starring Bill Bixby. He was the first David on "Eight Is Enough", only the first episode.
