Depends if you want to be them twins (say that they have too look exactly like the male character) OR are you looking for someone that might fit in the same role (which they don't have to look exact the same)
If so, then it shouldn't be that hard:
For example Davom Salvatore (seductive, but with a darker side): Eva Green, Katherine Moenning, Emily Blunt, Ana Ularu, Meghan Ory, Megan Fox, Serinda Swan
