Watched the actual movie,
Whatever Happened To Baby Jane, on TCM this morning. Jessica has the same facial structure as Crawford but only slightly resembles her. Susan, OTOH, is nearly a dead-ringer for Bette, especially in the make-up. At one point, Bette turned to look over her shoulder and the resemblance was striking. Oh, and the fellow who plays Victor Buono is scary-close, too. The film holds up pretty well, the only thing that really dates it is the soundtrack. Knowing about the backstage fun and games gives one a different view of the movie. Quite interesting.
