HALLE BERRY WILL PRESENT SAG AWARD
The Screen Actors Guild has announced that two-time SAG Award winner Halle Berry will be a presenter at the upcoming Screen Actors Guild Awards.
Berry won the award both times she was nominated. She won in 2000 for outstanding performance by female actor in a TV movie or miniseries ("Introducing Dorothy Dandridge"), and last year for female actor in a leading role in a motion picture ("Monster's Ball").
The SAG Awards will be presented on March 9 at the Shrine Auditorium in Los Angeles, in ceremonies to be televised by TNT.
OSCARS ON PARADE
The Academy of Motion Picture Arts and Sciences will put more than 100 Oscar statuettes on display as part of its diamond anniversary celebration.
The exhibit -- titled "And the Oscar Went To..." -- will feature Katharine Hepburn's Oscar for "Morning Glory" (1932/33), John Wayne's statuette for "True Grit" (1969), and all five Oscars from the 1975 sweep of the top categories by "One Flew over the Cuckoo's Nest." That will include the best actor and actress awards for Jack Nicholson and Louise Fletcher, Milos Forman's best director Oscar, and the statuettes for screenplay and best picture.
Organizers said they hoped to display all 15 of the statuettes presented at the first Academy Awards in 1928. They have already located 10 of those awards and confirmed that they will be available for the exhibit.
The exhibit will also feature Irving Berlin's Oscar for the song "White Christmas" from the film "Holiday Inn" (1942), Karl Malden's supporting actor award for "A Streetcar Named Desire" (1951), Francis Ford Coppola's screenplay Oscar for "The Godfather" (1972) and John Williams' music score Oscar for "Star Wars" (1977).
The exhibit, running Jan. 24 through April 17, is free and open to the public.
RICK SCHRODER'S NEXT
Rick Schroder ("NYPD Blue," "Silver Spoons") has signed to guest-star on two upcoming episodes of NBC's hospital comedy "Scrubs."
Schroder will play a love interest for Dr. Elliot Reid (Sarah Chalke) in episodes scheduled to air on Jan. 30 and Feb. 6. The story calls for Reid to fall for Schroder's character, thinking he is a fellow physician -- only to discover that he is actually a nurse, which forces her into an unexpected ego-check.
ABC OUT OF 'PRACTICE'?
According to Daily Variety, ABC faces a complicated decision that could lead to cutting the Emmy-winning legal drama "The Practice" from its primetime schedule.
The network holds the rights to the series for the 2003-04 season, but Variety said ABC executives are likely to ask 20th Century Fox Television to reduce its cost -- currently set at $6 million per episode for next season. The show consistently won its timeslot in the ratings last season, but Variety reported that network executives don't believe the current Nielsen numbers are strong enough to justify the cost of acquiring the show.
Sources said 20th and series creator David Kelley are open to the idea of a lower license fee, but that they also have an option to shop the show to other networks if they don't want to accept ABC's offer.
HONORS FOR MIKE MYERS
The festival -- running Feb. 26-March 2 in Aspen, Colo. -- will lead off with the Comedy Film Honors, recognizing the top comedy movies and actors of 2002.
