The Last Picture Show (Film Forum, 209 W. Houston, closes Thursday). Peter Bogdanovich’s classic 1971 study of small-town life in postwar America is now showing at Manhattan’s Film Forum in a brand-new print. Eileen Brennan, Jeff Bridges, Ellen Burstyn, Ben Johnson, Cloris Leachman, and Cybill Shepherd are all amazingly, even startlingly true to life. Yes, they really did make better movies in the Seventies, and this was one of the very best of the lot (TT).
