As a counterpoint to Wednesday night's Oscar glitter, the Golden Raspberry Awards Foundation presented its dubious honors for the worst film achievements of the year. Sylvester Stallone was named worst actor for "Rambo III," his third razz in five years. (He also "won" in 1985 for "Rhinestone" and in 1986 for "Rambo: First Blood Part II" and "Rocky IV.") Tom Cruise's "Cocktail" was selected worst picture for 1988. Others getting Razzies included Liza Minnelli for worst actress ("Arthur 2: On the Rocks" and "Rent-a-Cop"), Dan Aykroyd for worst supporting actor ("Caddyshack II") and Kristy McNichol for worst supporting actress ("Two-Moon Junction"). The Razzies are voted on by about 200 publicists.
