WATCH: Emma Watson, Logan Lerman & Ezra Miller discuss The Perks of Being a Wallflower

Hermione who?  Emma Watson has cast off her Hogwarts uniform and good girl image to play the broken Sam in Stephen Chbosky's adaptation of his own novel, The Perks of Being a Wallflower.

Last night The Cinema Society, along with Lancome and Nylon, hosted a special screening of the teen flick at the hip Crosby Street Hotel in Soho - just the kind of event the quirky characters in the film would have loved to attend!

But their alter egos were there, as Watson was joined by co-stars Logan Lerman and Ezra Miller.  Not only are their performances in the film impressive, but also the respect they have for Chbosky's novel and the intense issues it addresses.

Plus, you have just got to hear Miller's history with The Rocky Horror Picture show!

It's all in the video below - check it out!
