Nicholas got his first break at age 7, when he appeared as a young Tony Micelli (Tony Danza’s character) in a Who’s the Boss? flashback sequence. He went on to do several TV and film roles, including Married with Children (1989) and the 1993 film Rookie of the Year. Then came his breakout hit as Kevin in American Pie. Here we see him in eighth grade at the Laurel Hill School in North Hollywood, California.
