Harris' ABC teen prodigy dramedy, created by Steven Bochco and David E. Kelley, premiered on Sept. 19, 1989, when the actor was 16 years old. It would go on to run for four seasons. Harris tells USA Today the milestone makes him "feel like I've lived a whole lot of chapters, adding: "I look back on that with fondness. That was a very remarkably wonderful chapter for somebody who had never really been in the entertainment business before."
