Actress Katie Leung was stunned to land a role in the new Harry Potter movie - because she only went to the audition for the experience.

Leung, who plays Harry's love interest CHO CHANG in THE GOBLET OF FIRE, had set her heart on a career in interior design, when her father saw the Harry Potter casting session advertised on television.

She tells Total Film magazine, "I wanted to be an interior designer.

"I only went to the audition because it would be an experience."
