The Academy of Motion Picture Arts and Sciences is giving the devil his due tonight with a 40th anniversary screening of Roman Polanski's landmark thriller "Rosemary's Baby" at the Samuel Goldwyn Theater. While Mia Farrow plays Satan's Baby Mama and John Cassavetes is her husband (both pictured), Ruth Gordon, in her Oscar-winning supporting performance, steals the proceedings as the colorful neighbor Minnie, who just happens to be a witch. The evening also is a salute to producer Robert Evans, who brought the film to Paramount and shepherded the production. Evans will be on hand for an onstage panel discussion with Peter Bart, Brett Ratner, Sumner Redstone and Slash. Yes, really. (oscars.org). . . . Though most critics penned scathing reviews of Michael Cimino's lengthy, extravagantly over-budget 1980 "Heaven's Gate," former Times critic Kevin Thomas was one of the film's champions. Thomas presents the restored and uncut version -- clocking in at 219 minutes -- this evening at the American Cinematheque's Aero Theatre. . . . The Art Directors Society celebrates the career of William Creber ("The Poseidon Adventure," "The Towering Inferno") Sunday at the Egyptian with the gritty but dated 1968 Frank Sinatra police thriller "The Detective," for which Creber supplied the art direction. Creber will also discuss his career. (americancinematheque.com). . . . Sam Peckinpah changed the face of westerns with 1969's "The Wild Bunch," starring William Holden and Robert Ryan. AFI screens it Wednesday at the ArcLight Hollywood (afi.com). . . . Fittingly, few seats are left for the Los Angeles Conservancy's Last Remaining Seats fest, starting Wednesday with "Gentlemen Prefer Blondes." Check for standby tickets (laconservancy.org).
