Lisa Bonet
Her exotic looks and “The Cosby Show” platform made her national sex symbol and had millions of urban boys needing drool cups to handle the run-off. Through Denise Huxtable, Bonet had such star power back in the day that Cosby decided to make her the feature for a spin-off show, “A Diff’rent World.” But the former fashionista who used to dance to beat of her own drum took a sharp left turn with the weird and spooky “Angel Heart,” opposite Hollywood freak Mickey Rourke and her career has never been the same. She has starred in a slew of B-level movies and has made a series of guest appearances, but she never recaptured that “it” factor that shined so brightly during her Cosby years.
