Laurence is probably most famous for his roles in The Matrix and, more recently, Black-ish. The real ones will remember him from Pee-Wee's Playhouse as Cowboy Curtis. But his acting career goes wayyyy earlier than that since his first credited role was back in 1972 in the TV movie If You Give a Dance, You Gotta Pay the Band. Here he is in his second-ever role in the movie Cornbread, Earl, and Me in 1975, when he was only 14 years old.
