Devotees of Astaire and Rogers should note that the Biograph will be reviving FOLLOW THE FLEET and SWING TIME this weekend, while the AFI Theater hosts a Saturday matinee of "The Gay Divorcee" and "Shall We Dance." An ideal day for total immersion in perhaps the most satisfying romantic illusion Hollywood ever sponsored. For silent screen passion at its ripest, please note the double-bill of LOVE, the Garbo-Gilbert version of ANNA KARENINA and Valentino's SON OF THE SHEIK, Sunday and Monday at the AFI Theater.

y The Washington Area Film/Video League is sponsoring a two-day seminar on FEATURE PRODUCTION conducted by Edward Beyer, Saturday and Sunday from 10 to 4 at Musifex, Inc., 2420 Wilson Boulevard in Arlington.

y The Circle management has postponed the opening of the fine new Hungarian feature TIME STANDS STILL until next Friday. Meanwhile, MOONLIGHTING remains in the wings. Nino Manfredi's comedy-drama about a fantasizing Italian husband, PORTRAIT OF A WOMAN, NUDE, prematurely announced for an opening this weekend when it was shown last Sunday at the AFI, is positioned further back in the chain's waiting list of imports.

y Dyan Cannon and Lillian Gish have agreed to inaugurate WOMEN AND MOVIES III, a 10- day series organized by Women in Film and Video and the AFI, by introducing a showing of one of Gish's silent triumphs, Victor Sjostrom's THE WIND , on March 4. According to etiquette of the occasion, Cannon in her capacity as "Honorary Festival Chairperson" (oi!) will present Gish as "Guest of Honor." Gillian Anderson of the Library of Congress's Music Division will conduct her arrangement of the original score at this special presentation. A new feature, Susan Seidelmann's SMITHEREENS, will conclude the festival on March 13. The programmers have acquired the local premieres of such recent features as "Dirty Dishes" by Joyce Bunuel (Luis' daughter-in-law) and "Sally and Freedom" by the former Swedish actress Gunnel Lindblom, plus a rare revival of the vintage French film LA MATERNELLE , made by Marie Epstein in collaboration with Jean Benoit-Levy 50 years ago. Call 828-4087 for program information about the series. Ticket prices will range from $3 to $6, with AFI or WIF members eligible for discounts of a buck on each program.

y The excellent Hungarian film ANGI VERA, a substantial art-house success here in 1980, has been booked for a series of three benefit showings by the Community Relations Committee of the Washington Hebrew Congregation. Proceeds from the $5 admission price will go to the construction of Wallenberg House, a shelter for homeless families. "Angi Vera" will be shown at 7:30 and 9:30 on March 5, and 2:30 on March 6 at Massachusetts Avenue and Macomb Street NW. Call 652-2485 or 320-3633.

y Bonnie Schwartz is reviving her beginning FILMMAKING COURSE FOR CHILDREN, "Bug Flicks," designed to use the insects on display in the Museum of Natural History as camera subjects and potential "characters," at the Smithsonian for six Sundays from March 20 through May 1. There are two 90- minute sections. A morning group, meeting at 10:30, is open to ages 10 to 12. The afternoon session begins at 1 for prospective filmmakers ages 7 to 9. The fees are $38 for Smithsonian members and $48 for non- members.

y Francis Coppola's THE OUTSIDERS, a no-show last fall and winter, now appears signed, sealed and deliverable for March 25. Meanwhile, the American remake of Jean-Luc Godard's BREATHLESS, starring Richard Gere in an L.A. variation on the Belmondo role, has dropped out of the March schedule and receded in the general direction of early summer. Likewise for the next Woody Allen comedy, tentatively called "Zelig," probably a title destined for future trivia quizzes. BLUE THUNDER, tentatively scheduled to buck the same late-May opening day (Wednesday the 25th) reserved for RETURN OF THE JEDI, will now take off two weeks earlier, in pursuit of the early early summer jump.

y Finally, Judy Riggin, an associate professor of English at Northern Virginia Community College, may have contrived the ultimate spring movie course. Called FILM STUDY ABROAD: THE CANNES FILM FESTIVAL, it's a 16- day plunge into the Cannes whirpool, scheduled to begin May 6, for college credit yet. Enrollment is limited and the deadline approaches, so contact Riggin at 323-3353 or 323-3193 for further information.
