From Bloody Disgusting:
Bloody Disgusting has learned exclusively that Lily Collins (The Blind Side, Priest, Mirror Mirror)... is the female version of Ash, once donned by Bruce Campbell in the original trilogy. Fede Alvarez directs the redo of Sam Raimi's cult classic 1981 The Evil Dead from his own screenplay co-written with Rodo Sayagues. Revisions were done by Oscar-winning writer Diablo Cody.
That seems a little misleading, because by all accounts it sounds like the remake is going in a completely different direction than the original as Raimi and Campbell opted to not reproduce the Ash character. But even though she's not playing Mr. McChinnychin, it's nice to see some nice strong eyebrows on this Collins chick.
