LOS ANGELES (AP) -- Villainous roles have snatched the supporting-acting prizes at the Academy Awards: "Precious" co-star Mo'Nique as a loathsome mother and "Inglourious Basterds" co-star Christoph Waltz as a sociable Nazi fiend.
With the industry's top trophy in hand, both performers capped remarkable years, Mo'Nique startling fans with dramatic depths previously unsuspected in the actress known for lowbrow comedy and Austrian-born veteran Waltz leaping to fame with his first big Hollywood role.
