Born in 1956, the former medical student started his acting career in 1979, as the teenage son on the short-lived sitcom Shirley! Only 13 episodes were filmed, but that was enough for the teen magazines to adulate Peter as the Next Big Thing.

Besides, Matthew had a girlfriend, there was no homoerotic buddy-bonding, and there was not enough beefcake. Most gay kids quickly changed the channel to The Dukes of Hazzard on CBS. Powers was cancelled after only 22 episodes.
