IN HOLLYWOOD, DECEMBER MEANS TWO THINGS: HOLIDAY MOVIE premieres—and party time. For the cocktail-and-canapé crowd, invitations to celebrate—as many as three times in a single evening—have been arriving faster than rewrites to a troubled script.

At the Directors Guild of America on Dec. 4, Steven Spielberg took a break from hyping Hook to join with Jodie Foster, George Lucas, Sean Penn and other behind-the-camera types for talk about exorcising some artistic demons: colorization, altered sound tracks and other TV tampering with their works.

There was no time for too much indignation, though, since several of the guests, including superagent Michael Ovitz, had to hurry across town to the Beverly Hilton, where Lilly (Mrs. Brandon) Tartikoff was hosting her annual black-tie Fire & Ice Ball fund-raiser for the Revlon/ UCLA Women's Cancer Research Program. Among those on hand there: Candice Bergen, Kirstie Alley, Roger Moore and Sean Young.

Meanwhile, at the Beverly Hills restaurant Jimmy's, Robert Wagner, Tori Spelling and 200 others were singing "Happy Birthday" to Monica Seles, the 18-year-old tennis star who has been hinting of a move to L.A. to study acting. "I hope this is where my future will be," Seles confirmed. Which makes sense—if she can volley small talk as well as she does tennis balls.
