Scene-stealing, 8-year-old Jaden Smith plays 5-year-old Chris Jr. in The Pursuit of Happyness. This is Jaden's big screen debut, and he says "it was cool" working with his dad.

So how did Jaden cry so well during emotional scenes? "I just thought of sad things," he says.

Will remembers one day on the set when Jaden struggled with a crying scene. "I said, 'Listen, you know, you're an actor and you are a wonderful actor. … And we will all stand here and wait and when you're ready…,'" Will says. "And he stood there for a few minutes … but he took himself there and I almost messed the scene up because I was, like, 'Boy, why didn't you say you could do that?'"
