And you thought the stars on celebrity Fear Factor were D-list. For its upcoming reality series The Surreal Life — described as MTV's Real World but with a cast of has-beens — the WB has lined up rapper M.C. Hammer, Webster's Emmanuel Lewis, The Facts of Life's Mindy Cohn and former Baywatch babe Brande Roderick. What, no Ralph Macchio? All the excitement gets underway early next year. Meanwhile, Fox is doing a third edition of Celebrity Boxing in November. Casting execs are currently scraping the bottom of the barrel for participants.
