With songs by George and Ira Gershwin sung by Ginger Rogers and Fred Astaire, the 1937 musical Shall We Dance certainly begins this Wednesday night repertory series on the right note. In their seventh screen coupling, Fred and Ginger play famous hoofers on a Broadway-bound ocean liner, when scurrilous gossip . . . oh, who cares about the flimsy plot? All you need to know is that they sing and dance classic numbers including “Let’s Call the Whole Thing Off” (on roller skates!), “They All Laughed,” and “They Can’t Take That Away From Me.” It’s bliss in black and white. And, lest you think it’s all top hats and high heels, next Wednesday is An American in Paris; future weeks include Jim Jarmusch’s Dead Man, The Blues Brothers, and Purple Rain. That’s right—Purple Rain! With Morris Day! See Landmark’s Web site for full schedule and details. (NR)
