Epiphany: Karl Urban is the Kevin Bacon of genre films.

This came to me when someone asked me, "Why do we fall, Bruce?" thus quoting Linus Roache in Batman Begins, which made my mind jump to Linus Roache playing The Purifier in Chronicles of Riddick with Karl Urban.
Then my friend tossed out Mike Mignola, thinking a comic book artist would stop me short, but Mike Mignola draws Hellboy, which has Doug Jones as Abe Sapien, and Doug Jones played a zombie alien in Doom with *drumroll* Karl Urban!
Leave your Sci-Fi/Fantasy actors in the comments and challenge other GQMFs to find the chain! Bonus points if you can stay within genre for every step of the way. I haven't figured out a chain for Arnold Schwarzeneggar that doesn't veer out (Schwarzeneggar as Mr. Freeze in Batman and Robin with George Clooney, who was in Ocean's Eleven with Matt Damon who [sob] killed assassin!Karl in Bourne Supremacy, or Terminator 2 with Edward Furlong who was in American History X with Edward Norton who was in The Incredible Hulk with Liv Tyler who (poor thing) didn't get to share screen space with Karl in Lord of the Rings).
I DARE YOU TO DO BETTER.
