Logan Lerman and Emma Watson in The Perks of Being a Wallflower

Harry Potter's Emma Watson and Percy Jackson's Logan Lerman are considering starring roles in The Perks of Being a Wallflower, based on the 1999 book by Stephen Chbosky. Variety says Chbosky adapted his own book and will be directing the feature film. Chbosky's never directed a feature film before, but did adapt Rent for the big screen and was a writer on the now-cancelled TV series, Jericho.

In The Perks of Being a Wallflower, high school student Charlie writes a series of letters to an unnamed person chronicling his life as he experiences all the trials and tribulations of being a teenager. Lianne Halfon, John Malkovich and Russell Smith are producing. There's no word yet on when production is expected to begin.

Watson has the final two films of the Harry Potter series set to be released in November 2010 and July 2011 and then she'll be completely finished with playing the character she'll forever be most associated with: Hermione Granger. Logan Lerman recently signed up for Paul W S Anderson's 3-D The Three Musketeers set up at Summit Entertainment.
