Where Have I Known You Before, Part Deux

I finally relented and checked IMDb to see where I had "Terrence Steadman" from Prison Break before. Turns out he was Dr. Phlox on Star Trek: Enterprise. I like to think I would have figured it out eventually. I probably wouldn't have gotten that Leonard Betts from the X-Files episode of the same name is part of the shadow chamber that has suddenly appeared on 24, especially since I can't seem to find the credit for him for the latter.

I also didn't connect Bernard from Lost to Holland Manners from Angel until someone pointed it out, but I was thrown off by the character not being, you know, evil. Although looking that up shows me that Josh Holloway (Sawyer) played "good-looking guy/vampire" in the latter show's pilot.
