I think Shaun Cassidy created Invasion, not Surface. He also created this show a few years back called American Gothic, which was actually pretty cool. ROARRRRRRRRRRRR! (LMAO - people, you MUST watch the opening credits)
Nice to see Shaun Cassidy didn't end up like fellow 70s teen idol and current train wreck Leif Garrett (on a personal note, my major 70s crushes were David Soul (OK that's scary) and Richard Hatch (not naked Survivor and tax fraud convictee Richard Hatch, but original Battlestar Galatica Richard Hatch - who knew they had feathered hair and discos in space?!)
