Singer-actor Will Smith says that it is rare for a black man to play a racist on the big screen, and found it 'really bizarre' to essay such a character in the upcoming movie Bright.

Bright takes place in a world where human lives alongside fairytale creatures such as orcs and elves, and rather than showing racism between humans, the movie explores the tensions between people and creatures.

"As a black dude you just don't get a lot of movies where you're a racist. It's rugged and powerful and really bizarre for me to be on the other side of that," says Smith.

He wasn't the only star who struggled with his role, as his co-star Noomi Rapace couldn't get to grips with wearing contact lenses and a false set of teeth when she first took on her role, although she soon adapted. "I was fighting against the contact lenses and teeth at the beginning. But it's amazing how quickly you adapt," she says.
