The SAG awards, to be presented on Feb. 5, is widely regarded as a barometer for the Oscars, which will be presented on Feb. 27 by the Academy of Motion Picture Arts and Sciences.

"Sideways," a low-budget movie, has already been named as 2004's best movie by several critics groups, and the SAG nominations will help boost its Oscar hopes because many SAG members are also Academy members.

He was also in the best cast category for "Ray."

Along with Church and Foxx, other supporting actor nominees were Morgan Freeman for "Million Dollar Baby," child actor Freddie Highmore in "Neverland" and veteran James Garner in romance "The Notebook."

In addition to Madsen, supporting actress nominees were Cate Blanchett, which portrays screen legend Katharine Hepburn in "Aviator," veteran Cloris Leachman in comedy "Spanglish," Laura Linney in "Kinsey," which is about sex researcher Alfred Kinsey, and Sophie Okonedo in "Rwanda."
