Peter Ustinov didn't get much time to chat with the queen when the actor was knighted at Buckingham Palace.

Ustinov, best known for his movie role as Agatha Christie's Hercule Poirot, was one of 130 recipients of honors bestowed Tuesday by Queen Elizabeth II."She said, `I hear you're still as busy as ever,' which I thought was very nice," Ustinov - now Sir Peter - recalled. "I said, `Yes, I've just been to Australia and New Zealand,' and by that time the next man was on."

The son of Russian and French parents, Ustinov served for years as a roving ambassador for UNICEF and UNESCO. He rose to stardom in such films as "Spartacus," for which he won an Oscar for best supporting actor.
