If you could be any character from any movie who would it be?

Personally, I would want to either play Sarah Conner in "The Terminator...(Just because it's a fun and fiesty role) or Rose from Titanic. (Because the costumes she gets to wear are...AMAZING!!!) or Ripley from "Aliens" (Because she's such an awesome bada**) What do you guys think? (And yes I adore James Cameron!)
