I've just been luring on this thread, but loving all the suggestions. Skywalkersaga, I LOVE that Peter Steele is on your list. I saw Type-O on Halloween, must have been around 96/97. Steele was so HUGE. He came out on stage with a bottle of wine in his hand, and he was so big it looked like a beer bottle. Hell of a show.
I don't have a solid 5, but number 1 on my list (and this is a weird one) would be a young Elias Koteas:
Such an under rated actor. Not only was he the definitive Casey Jones in the old Teenage Mutant Ninja Turtles movie, but he had some of my all time favorite roles, in stuff like Some Kind of Wonderful, Thin Red Line, Gattaca, and The Prophecy, not to mention Cyborg 2 (which is kinda terrible, but there's also something wonderful about it, with a cast that includes Jack Palance, Billy Drago, and might actually be Angelina Jolie's 1st real role). He just brings a lot of charisma and personality to everything he's in. It's actually a head that I've wanted to see made for a really long time.
And I'd have to say Shirley Manson from Garbage.
Garbage has been around for over 25 years at this point, and I still have such a ridiculous crush on this woman. Gorgeous, super smart and iconic, one of my favorite singers of all time, and absolute cool. And she was a terminator on The Sara Conner Chronicles!
