Sir Ben Kingsley admits that the most challenging part of making new adventure movie 'Prince of Persia: The Sands of Time' was getting to grips with riding a horse.
He explained: "Horses make me very nervous. It's not that I don't really like horses but rather they don't like me.
"I did have to do some riding and then I was in a full suit of black armour - and then it decided to be 120 degrees. It was awful."
Kingsley adds he loved the character, but is not at all like Uncle Nizam.
He stated: "My character, Uncle Nizam, isn't a baddie. This was a man driven by envy and regret. He was a normal chap and when envy started to eat away at him, he turned bad. With that richness of character in mind, I was on that knife-edge of being good and bad, which I love.
"I'm not Uncle Nizam, eaten up with envy and regret. I'm a happy man, and maybe it's because I let things pass."
The Oscar-winning actor also claims stays away from movies if he does not like the director.
He told the Hollywood Reporter: "I avoid working with directors who are bullies and patronising and really don't understand the process of creation in front of the camera. I wouldn't work in a film that I felt wasn't a bridge builder."
