London, Aug 21 - 'Harry Potter' star Daniel Radcliffe's desire to direct a movie is not a secret, but the young actor is apparently keen to wield the megaphone for a gangster movie.

Thesun.co.uk reports that the 20-year-old actor spends a lot of time looking for a suitable script.

'Daniel's been looking at lots of scripts trying to decide what he'd like to direct. But he's now focusing on a story about a London gangster. He wants to challenge people's pre-conceptions of him,' said a movie insider.

Radcliffe plans to direct a movie after he finishes the last instalment of the 'Harry Potter' series.
