Dramatic departures: Can the TV show go on?

LISA BONET: Backlash from a nude scene in the movie "Angel Heart" as well as Bonet's pregnancy with husband Lenny Kravitz may have prompted her early exit from "The Cosby Show" in 1988, but the actress ended up on "Cosby" spinoff "A Different World." She quit that show before it ended, too, and returned for several appearance on "Cosby." chris pizzello / AP
