Keira Knightley

The similarity between Knightley and Natalie Portman meant that during the filming of Star Wars: Episode I - Die dunkle Bedrohung (1999), their own mothers could not tell them apart once in makeup.

The problem for me was that by being in the film the magic was broken. I loved the first Star Wars film and my mum was really into it too, that's why I took the part. But the Force wasn't there when we were filming it, and they didn't have real light sabres, which annoyed me.
