A lot of genre favorites are based -- or so it's claimed -- on play, but who's actually read these things? I've read DRACULA, THE GHOST BREAKER and THE CAT AND THE CANARY, but that's about it. I've never come across the play of THE BAT, though I've read the novel or novelization. FRANKENSTEIN existed in play form, but has anyone ever seen it? What about this play that DOCTOR X is adapted from? Has anybody ever even discerned the title?
