It’s Freddie Bartholomew day on TCM, an all-day salute that includes, in prime time, two favorites: 1937’s Captains Courageous at 8 p.m. ET, and 1938’s Kidnapped at 10:15 p.m. ET. The rarity, though, arrives very late at night, when Bartholomew makes a camera appearance, as himself, in a 1947 musical that’s rarely televised: Sepia Cinderella, a film aimed primarily at black audiences, and including lots of nightclub acts popular at the time.
