Anne of the Thousand Days--A boring re-enactment of the Ann Boleyn-Henry VIII conflict that's inaccurate to boot. Genevieve Bujold's Anne, however, is lovely, and almost makes the film worth seeing. With Loves of Isadora, a mess, but a showcase for Vanessa Redgrave's great talent. ORSON WELLES CINEMA, Call 868-3600.

Dirty Harry--A hack detective thriller directed by the talented Don Siegel from a script laden with authoritarian preaching. Clint Eastwood, perhaps the least talented superstar of all time, is Harry. With The Omega Mess, Charlton Heston in humdrum sci-fi. ASTOR. Harry: 1:15, 4:40. Omega: 3, 6:25, 9:45.

Garden of Finzi-Continis--Overrated. A very heavy and sentimental Vittorio De Sica flick about the round-up of Jews in Fascist Italy. Features the most ineiegant rich clan since Visconti's The Damned. CINEMA KENMORE SQUARE, 1:45, 3:45, 5:45, 9:30.

Lawrence of Arabia. David Lean's best film. If the music is cliche and some of the post-release cutting execrable, Peter O'Toole's performance is classic--one of the few convincing portrayals of a man of genius in film history. The story is a guilt-ridden updating of the white man's burden myth, with sturdy construction and dialogue by Robert Bolt. HARVARD SQUARE THEATER, 2, 5:15, 8:30. Last day.

Play it Again, Sam--Very funny Woody Allen film with the comic starring as a film critic with a lousy sex life. CIRCLE, 2, 3:55, 5:50, 7:45, 9:50.

Satyricon--A vile Fellini phantasmagoria based on Petronius but lacking the wit and lightness of the epicurean's touch. With Marat Sade, Peter Brook's sensational and sensationalistic production of the finally incoherent Peter Weiss play. CINEMA 733 (Thurs. and Fri.) Call 266-0342 for times.

To Have and Have Not. Bogart is an anti-Vichy gun-runner; Bacall, in her screen debut, gets to tell him if-you-need-anything-just-whistle. Forget Hemingway (the filmmakers did), but Faulkner helped write the script, Howard Hawks directed, Bogart is "Nietszche in dungarees" and Bacall's come-ons are hilarious. With Take the Money and Run, the first Woody Allen-directed comedy. HARVARD SQUARE THEATER. Call 864-4580.

White Shelkh--The first film directed solo by Federico Fellini and one of his best; hilarious comedy of misdirected lower-middle-class romance. With I Vitelloni, another of the great Fellinis, dealing with stunted lives in the Italian seacoast town of Rimini. BRATTLE (starts Wednesday). Shelkh: 8, Vitelloni: 6:15, 9:30.
