Who played rouge in all x men movies?

There's a bit of a tricky answer to this. The character of Rogue has been portrayed by two different actresses in the X-Men movie franchise:

* Anna Paquin played Rogue in the original X-Men trilogy (2000-2006): X-Men, X2: X-Men United, and X-Men: The Last Stand.

* Taylor Kitsch played a younger version of Rogue in X-Men Origins: Wolverine (2009).

This movie is a prequel, and as such, shows the backstory of Wolverine before he became a part of the X-Men. This film's version of Rogue isn't considered canon by many fans.
