Harry Potter star on her new adventure

Emma Watson stars in a new apocalyptic film called This is the End. The former Harry Potter star says it is a big departure for her but that she loved the script.

The film is directed by fellow actor Seth Rogan and tells the story of six Hollywood stars who become trapped in a house after a series of strange events.

Watson took time out from the red carpet to tell reporters why she decided to be in the film.
