The American Film Institute's Silver Theatre continues exploring the works of the great filmmaker. Up this weekend: Spellbound (1945), starring Ingrid Bergman and Gregory Peck and featuring an iconic dream sequence designed by Salvador Dali and Miklos Rozsa's Oscar-winning, theremin-intense score. Watch carefully -- if you're lucky, AFI has a version of the black and white film that includes a carefully placed flash of color. It's a startling effect. Also showing is Lifeboat, Hitchcock's inventively staged drama, set entirely on a lifeboat. It was a big hit with wartime audiences though some critics faulted it for not being more patriotic. Tahllulah Bankhead, giving a razor-sharp performance, steals the film. Watch for Hitchcock's traditional cameo in a weight-reduction newspaper ad. Spellbound screens Saturday, May 13, at 7 p.m., Wednesday, May 18, at 9:15 p.m., and Thursday, May 19, at 9:15 p.m.; Lifeboat screens Sunday, May 14, at 12:30 p.m., Tuesday, May 17, at 9:15 p.m., and Thursday, May 19, at 7 p.m. AFI Silver Theatre, 8633 Colesville Road, Silver Spring. Tickets are $11 for each screening. Call 301-495-6720 or visit afi.com/Silver.
