Ralph to play Voldemort

Ralph Fiennes will star as the evil warlock Voldemort in the fourth Harry Potter movie.

Voldemort is so bad the characters in JK Rowling's stories try not to speak his name aloud.

He has been deprived of a body for the first three films after a spell meant for a baby Harry Potter backfired - but Voldemort returns in the flesh for Harry Potter And The Goblet Of Fire.

Filming started on 25 June although Fiennes, who also played a bad guy in Red Dragon, has not yet been involved in these scenes.
