Temple playing Harley Quinn?

According to Variety's Jeff Schneider, Juno Temple is rumoured to be playing Harley Quinn in The Dark Knight Rises. This is very much unconfirmed, and should be taken with a grain of salt. Furthermore, IMDB claims that she is playing Holly Robinson. For now, she is simply a "street-smart Gotham girl."

Temple is the daughter of British filmmaker Julien Temple. She has previously starred with Emma Roberts in Wild Child, Atonement with James McAvoy, Mr. Nobody and Glorious 39 with Toby Regbo and Greenberg with Ben Stiller. She will appear in the upcoming The Three Musketeers with Orlando Bloom.

Harley Quinn is the sidekick of The Joker (Heath Ledger), whilst Holly Robinson is the best friend and sometime accomplice of Selina Kyle/Catwoman (Anne Hathaway).
