Watson has been busy since the "Harry Potter" franchise concluded. In 2012 she toplined as one of three troubled teens in "The Perks of Being a Wallflower," while the 2013 pipeline holds Sofia Coppola's "The Bling Ring." The actress has also finished shooting Darren Aronoksky's Old Testament epic "Noah," Seth Rogen comedy "This is the End," and is attached to depression drama "Your Voice in My Head," adapted from Emma Forrest's memoir.

He also starred in 2013 Sundance entry "Kill Your Darlings" as young poet Allen Ginsberg.
