The title of Gayle Pemberton's essay "Do He Have Your Number, Mr. Jeffrey?" comes from an offscreen line in Alfred Hitchcock's Rear Window. The speaker was a babysitter, but the character's infantile drawl -- the old stereotype of black people as dawdling, servile simpletons -- makes her sound as if she could use a babysitter herself. The 1991 essay is, among other things, about what it means to be a black fan of classic Hollywood movies. Pemberton isn't a breathless, gushing movie buff. Hers is a canny love, beneath which lies the needling reminder of a history that stereotyped and demeaned black characters more often than it treated them straight, and that mostly just plain ignored black performers.
