The Oscarsare nearly upon us. Are you still clueless as to why insiders have pegged "An Inconvenient Truth" as a shoo-in for Best Doc Feature? Or are you looking for a last-minute (and we mean down-to-the-wire, folks) screening of "Jesus Camp," the controversial film about a North Dakota Christian camp that trains kids for "God's Army"?

The National Archives is in the midst of screening every last one of the nominated movies in four categories: Documentary Feature, Documentary Short Subject, Live Action Short Film and Animated Short Film. And unlike similar screenings in the area, these are totally free and come complete with special introductions by other filmmakers and film experts.

Start with the showing of the Al Gore juggernaut "An Inconvenient Truth"tomorrow. Flo Stone, artistic director and founder of the D.C. Environmental Film Festival, introduces the movie. (Free tickets are distributed at the special events entrance on Constitution Avenue an hour before the films.) 7 p.m. Then catch "Jesus Camp"on Sunday at 4 p.m. Since its release, the film, by Heidi Ewing and Rachel Grady, has been cause for dismay for the Kids on Fire camp and its head, the Rev. Becky Fischer, who has announced that because of the backlash after the film's release, she's canceling sessions indefinitely.

On Saturday, make a day of seeing all the short films and animated shorts. Peggy Parsons, the National Gallery's head of film programming, introduces the first set at noon (the screening includes "Binta and the Great Idea," "The Saviour" and more); the animated films are screened in one sitting beginning at 3:30. National Archives, William G. McGowan Theater, Constitution Avenue NW at Seventh Street. 202-357-5000.

Speaking of all-day exercises in patience, AMC Theatres host screenings of all the Best Picture nomineeson Saturday -- five films in one go. We suspect that by the time you get to the last film, "Little Miss Sunshine," you won't be feeling very sunny yourself. (Catch screenings at area theaters including the Owings Mills 17, the Tysons Corner 16 and the Rio in Gaithersburg.) $30 includes light concessions. 11 a.m. http://www.amctheatres.com.
