Costumes advised at Fremont's last outdoor-movie event

This weekend in film-related irony:

Streaking is discouraged. Yeah, right: in Fremont. You know, naked-cyclists-in-body-paint-Fremont. Get back to me on that.

The occasion is the last show of the season at the Fremont Outdoor Movies, the adult-frat comedy "Old School" (2003, R), which prominently features Will Ferrell's naked, streaking, hairy and not terribly firm buttocks — as well as copious drinking.

As a warmup to next week's Fremont Oktoberfest, organizers are setting up a beer and wine garden, and having some games and contests at 7:45 p.m. Saturday before the movie rolls at 8:30.

Authority figures want you to show up in Oktoberfest or "Old School" costume, and as gracious hosts will provide togas for complimentary school pictures. No mention of beer bongs. $5 suggested donation, corner of North 35th Street and Phinney Avenue North (206-781-4230 or www.fremontoutdoormovies.com).

And although you would never dream of hauling off and streaking — in Fremont — remember that it could be chilly.

Your best bet for fully clothed late-night, indoor fun is "Donnie Darko (Director's Cut)" (2001, R), midnight tonight and Saturday at the Egyptian Theatre, 805 E. Pine St., Seattle (206-781-5755 or www.LandmarkTheatres.com). There's 20 minutes of extra footage in this version of the instant cult classic starring Jake Gyllenhaal as a troubled suburban teen who begins seeing a giant rabbit warning of the world's end after a jet engine crashes into his bedroom. Love the '80s soundtrack.

Meanwhile, the Grand Illusion is nearly bursting with cult filth: The 1981 chick-punk-rock flick "Ladies and Gentlemen, the Fabulous Stains" (R) plays at 7 and 9 tonight in honor of its release at long last on DVD. Continuing in a similar vein, the transcendently funny mock-doc "This is Spinal Tap" (1984, R) begins a weeklong run Saturday. Last and possibly distant least, "Viva" (2007), director/star Anna Biller's unrated paean to early '70s sexploitation cinema, featuring nudism, hippies, women's lib and more, 11 p.m. today and Saturday. 1403 N.E. 50th St. (206-523-3935 or www.grandillusioncinema.org.

For the cultural equivalent of a shower, the Northwest Film Forum continues its "Labyrinthine Alain Robbe-Grillet" series with "The Man Who Lies" (1968), 7 p.m. Saturday and 9:15 Sunday, and "Eden and After" (1971), 9:15 Saturday and 7 p.m. Sunday.

Also, starting Tuesday, a new series, "Milos Forman's Formative Films," with "Audition" aka "Competition" (1963), 7:15 p.m. Tuesday and 9:15 p.m. Wednesday, and "Black Peter" (1964), 9:15 p.m. Tuesday and 7:15 p.m. Wednesday. See how they swap those around? All NWFF events take place at 1515 12th Ave., Seattle; for more information, see www.nwfilmforum.org or call 206-267-5380.

Metro Classics continues to serve out its tour with director John Boorman's "Hell in the Pacific" (1968, G), with enemies Lee Marvin and Toshiro Mifune stranded on an island, 7 and 9 p.m. Wednesday only, Metro Cinema, 4500 Ninth Ave. N.E. (206-781-5755).
