Notable role (as a child): Joshua Hall in One Life to Live (1973-1976)

Best known for his role as Neo's mentor Morpheus in The Matrix, Fishburne made his acting debut at the age of 12 on the New York-based soap opera. And most people think he got his start working under Francis Ford Coppola on 1979's Apocalypse Now. That would've been a far more auspicious start.
