Emma Watson 'liberated' in new movie

Emma Watson has admitted that leaving her Harry-Potter alter ego behind has been liberating.

The 22-year-old-actress attended a gala this week for her first major post-Potter movie, The Perks of Being a Wallflower.

She plays the character Sam in the coming-of-age story based on Stephen Chbosky's novel, alongside Ezra Miller and Logan Lerman.
