*grins* I think Crichton fathers been doing a "Tooms" from the X-Files. I've just seen him alive in the late 1960s and he doesn't look a day younger. ;)
OK, what am I talking about? I've been watching the tapes I have of Dark Skies and in the middle of the season Loneguard visits his home for a while and guess who his father is...yup its the same actor. I can't remember his name atm tho and too lazy to go and check the tape.
The name of the actor that plays Crichton's father is Kent McCord. He also had a small role on the series Seaquest DSV that lasted for several episodes.
He was on Adam 12, with Martin Milner.
1-Adam 12, 1-Adam 12, see the woman...
Kent McCord was also in either Battlestar Galactica or Galactica 80 IIRC.
