I'll admit, I only know Richard Hatch from BSG, and even then mostly from Nu BSG. Yes, I have watched the original, but I started with the Nu series first, and so for me Richard Hatch is Tom Zarek more so than he is Apollo. And he was really good as Zarek, the kind of villain who you want to succeed, because it makes things far more interesting. Damn shame to lose him.
Damn, and only a few weeks after we lost John Hurt to pancreatic cancer too. While cancer in general is awful, pancreatic is one of the worse types.EDIT: OK, TMZ has confirmed it. Pancreatic cancer, went into hospice weeks ago
