I got to spend a couple of days at a sci-fi convention at a table next to Richard Hatch of the 1970s Battlestar Galactica fame. He was a really cool guy and we spent all day joking around. Every so often, someone would come by and say, “hey! You’re uh… uh…” and I would say, “he’s Dirk Benedict.” (That was his BSG co-star). Once I told a lady that she better not call him Dirk Benedict because it makes him really mad.
If I had a photo of Dirk Benedict, I would have asked him to sign it.
Sadly, Richard Hatch is no longer with us. I really enjoyed hanging out with him. He was way into tabletop gaming and even would leave the table sometimes to host a session. I’m not a huge TTGer anymore, but I wish I could have had Richard Hatch as a GM.
