Daniel Radcliffe has said he has "a huge amount to prove" to himself at the London premiere for his new film The Woman In Black.

The 22-year-old actor admitted he had not expected to be so nervous at the launch of his first film following the end of the Harry Potter series.

He also discussed his next project, Kill Your Darlings, in which he plays Beat poet Allen Ginsberg.
