I was watching this show today, and it was about Eight is Enough. Remember that show? Wow I used to watch that as a kid all the time! Anyways, I never realized the role of the oldest brother was originally cast for Mark Hamill. Imagine that! Of course, imagine what it would be like today if Mark Hamill had gone on Eight is Enough instead of Star Wars… Wow, how different would it all be today? I just wonder!
