SIR Anthony Hopkins takes great measures to reassure young actors he's no temperamental diva - because he knows how intimidating people can ruin a movie. The movie great takes trouble to personally meet his co-stars and insists they call him, simply, Tony in an effort to put them at their ease on set. He says, "I hope I don't intimidate people. I'm very easy to work with and I like to keep things light on the set. "Sometimes actors can dominate a set and make it miserable, or directors, certainly, can do a great deal of harm - you're not allowed to speak or make a mistake - and that's awful for everyone. "There are few of those around. I've worked with a few of them. They're horrors, so I try and buck the system and make light of them (on set)."
