Malcolm-Jamal Warner, the actor, who has died aged 54, was cast as Theo Huxtable in the sitcom The Cosby Show at the age of 13, and over the course of some 200 episodes became one of US television’s best-known teenagers.

Anthony Mackie recalls Malcolm-Jamal Warner's reaction after he sported Theo Huxtable's Gordon Gartrell shirt from "The Cosby Show" on "The Tonight Show."

As we mourn Malcolm-Jamal Warner, we give thanks for who he was as Theo and who he was a man in the real world.
