Matthew Perry will play “a charming sportscaster who tries to move on after a personal tragedy through the help of mandatory therapy sessions” in the NBC pilot Go On. The pilot’s writer and executive producer, Scott Silveri, worked with Perry on another NBC show called Friends. Maybe you have heard of it? It was on for a while, I think. Anyway, the reunion is fun and all, but I wouldn’t place all my bets on it just yet: shows by Friends alums have failed before.
