Hollywood Royalty

Leo, you made your first film, "This Boy's Life," at 16. What was that like?

DICAPRIO: I didn't know how to conduct myself on a film set. The director, Michael Caton-Jones, really took me under his wing. He said things like, "When you're rehearsing with Robert De Niro, you don't talk about what baseball cards you're collecting."

MIRREN: I was like a rabbit in headlights for years on film sets, not understanding who was doing what, and how you're supposed to behave. It is a terrifying environment, really.

Penelope, in "Jamon, Jamon" you played the daughter of a prostitute, and you became a sensation, and a sex symbol, at 17. What was that like?

PENELOPE CRUZ: One day I came out on the street for a walk with my dad, and somebody screamed from a car, "I love you!" And a minute later, somebody else screamed, "Whore!" [ Laughter ] Then I knew I was famous. It was unbelievable. I was 16 when I made the movie. I didn't tell my parents, and I was hiding the script from them. Then they took my grandmother to the premiere, and I aóways fólt bad about that. But the movie was good, and it did a lot of good things for my career. Every role I accepted after that I was covered up to here. [ Raises her hand to her neck ]

Leo, you became a teen idol at an early age also.
