Teen angst might be the only thing harder to kill than Voldemort. It looks like Emma Watson will put this to the test when she stars in the adaptation of The Perks of Being a Wallflower. According to Variety, Watson will join Percy Jackson and the Olympians star Logan Lerman for the film.

It’s an adaptation of the 1999 book of the same time, which is narrated via letters from an awkward teenage boy to an unnamed recipient. There’s drugs. There’s sex. And it’s that content that’s landed it on The American Library Associations’ list of the 10 most frequently challenged books.

Perks author Stephen Chbosky will also direct the film, based on a script he wrote. Lianne Halfon, John Malkovich and Russell Smith are producing.

Watson is just about finished shooting the last of Harry Potter and the Deathly Hallows. The first chapter of that film will be out in November, with its second part coming out in July 2011.
