EXCLUSIVE: As Deadline told you, Summit Entertainment post-Twilight Saga is continuing to bet heavily on books for its future franchises. Most are conducive to young casts. Now I can report that another young actress to watch is making the transition from TV to movies: CW’s The Vampire Diaries star Nina Dobrev has been cast as Candace in the film based on Stephen Chbosky’s novel The Perks of Being A Wallflower, which the author is adapting for Harry Potter‘s Emma Watson and Logan Lerman as well as Paul Rudd. This was a much sought-after lead role. The 22-year-old Bulgarian-Canadian actress played Mia Jones, the single teenage mother, on Degrassi: The Next Generation, from the show’s 6th to 9th season. She currently plays Elena Gilbert and Katherine Pierce on The Vampire Diaries and won the “Young Hollywood Making Their Mark” category at the 12th Annual Young Hollywood Awards. (Disclosure: these awards are owned by my parent company PMC).
