BAM Rose Cinemas’ salute to the leading men of French cinema turns tomorrow to Gérard Depardieu in Maurice Pialat’s “Loulou” (1980). He’s the loutish drifter Loulou, who finds himself in a torrid relationship with Nelly (Isabelle Huppert), who gives up her bourgeois lifestyle for one devoted to sex and booze. The theater is at 30 Lafayette Ave., off Flatbush Avenue, in Brooklyn; bam.org
