Grint - Harry Potter was 'my whole childhood'

10 November 2013 Last updated at 12:11 GMT

Actor Rupert Grint has said that starring in the Harry Potter series was like growing up in a "bubble" and left him initially not knowing what to do when he ceased to play Ron Weasley after eight films.

Despite being "nervous" of stage work, Grint told Andrew Marr he had thrown himself into the "hard work" of appearing in the West End production of Mojo, which tells the story of gang life in 1950s Soho.
