Dakota Fanning (Jane)

Fanning isn't only known for her work in the 'Twilight Saga,' but it has helped the star of blockbusters like 'War of the Worlds' and 'The Cat in the Hat' reach an even larger audience. Fanning's next steps include some more adult work: she'll play an 1850s teenage bride trapped in a sexless marriage in the Emma Thompson-directed 'Effie,' and team with 2011 It-Girl Elizabeth Olsen for 'Very Good Girls,' about two girls looking to lose their virginity. Scandalous!
