Saturday is a real "event" day for the United States Film Festival, with the winners of the independent competitions for documentary and dramatic films being announced in the evening at an awards ceremony, preceded by the world premiere of "The Big Picture" in the late afternoon.

Stargazers can fill their eyes at both: Director Paul Mazursky ("Moon Over Parador," "Down and Out in Beverly Hills") will emcee the awards show, with filmmakers and celebrity guests in attendance. At the screening, Kevin Bacon and director/co-writer Christopher Guest will introduce "The Big Picture"; Guest's wife, Jamie Lee Curtis, will also be there.The awards ceremony is closed to the public, of course, and the Saturday screening is sold out, but "The Big Picture" will also be shown Sunday, and tickets were still available at press time.

In fact, as the festival winds down and people depart Park City for home, the last Sunday is usually a good day to hit screenings, which include the films chosen as the top competition winners.

-SATURDAY'S BEST BETS: Documentaries "Isadora Duncan," "Coverup," "Comic Book Confidential" and "Lodz Ghetto" are all worth a look, and dramatic films "True Love," "Apartment Zero" and "84 Charlie Mopic" are popular contenders.

And you can bring the family to see the two Charlie Chaplin shorts, "One A.M." and "A Day's Pleasure," or the "Salute to Jay Ward," which features such cartoon favorites as "Rocky & Bullwinkle," "Dudley Do-Right" and "George of the Jungle."

The United States Film Festival is presented by the Sundance Institute, in cooperation with Utah Film Development. Festival officials suggest you phone ahead to check if seats are still available for the movies you want to see and to reserve tickets. The festival information line is 322-1700.
