She was also in a movie called "The Invisible". Quick sidenote on the movie, it was 1 of the first Scandinavian remakes (think Girl with Dragon Tattoo), but the ending was switched up in the remake, since Disney had an issue with the original ending, and the movie didn't fare as well in the US. So ML didn't really get traction with it. She also had appearance in "Revenge".
Anyway, I think her hair was at it best in "The Invisible"...she did cut a lot of it off for the premiere (I think) though.
