On the eve of Michael J. Fox's departure from ABC's Spin City comes word that the Pepsi-Cola Company will reair Fox's acclaimed 1987 Diet Pepsi commercial during Wednesday's episode of Spin as a tribute to the beloved actor. The company will also donate $100,000 to the Michael J. Fox Foundation for Parkinson's Research. "Michael's warmth, believability and unique comic timing helped us make some of the most entertaining commercials we've ever created," Pepsi exec Alan Pottasch said in a statement. "He is a true friend of Pepsi."
