Why Jeremy Miller Was "Bothered" by Leonardo DiCaprio

For seven years, actor Jeremy Miller played the pesky youngest son on the TV hit Growing Pains. Having started acting at age 5—and having landed his hit role at age 8—the child star often stole the scenes on the weekly sitcom.

"The whole cast, we really were as close as a family," Jeremy says. "I was lucky. We had the most amazing set a kid could ask for."

However, there was one thing Jeremy wasn't prepared for: the addition of a new cast member in 1991, played by then-unknown actor Leonardo DiCaprio. How did Jeremy feel about the addition, and were the two ever in competition?
