Richard Pryor and George Carlin are the most bankable stars of 1976’s Car Wash. Get a good look at them on the poster, however, because their combined screen time works out to less than 15 minutes; their humor contribution to less than zero. So why bother? How ’bout the fact that Franklyn Ajaye—the comic who gave us Don’t Smoke Dope, Fry Your Hair!—has a starring role? Or that this is your chance to see Lorraine Gary in something other than a Jaws movie? And then, of course, there is the amazing soundtrack, produced by Motown legend Norman Whitfield and performed by Rose Royce. But most of all, you get the lavender-hued prose of screenwriter Joel (Batman Forever) Schumacher, who has a queeny Antonio Fargas deliver these immortal words: “I’m more man than you’ll ever be and more woman than you’ll ever get.” The film screens at 7 p.m. at the Library of Congress’ Mary Pickford Theater, 101 Independence Ave. SE.
