There's a pest who likes gore and wrings necks
He's ingesting each corpse he dissects
To the touch he's synthetic
And his clutch is prosthetic
Film in question? The warped Doctor X.
Lionel Atwill and Preston Foster in Doctor X (Michael Curtiz, 1932), a twisted pre-code horror gem, eerily hued in two-strip Technicolor. Title by David Cairns, who laments that his favorite line in the film, "An empty sleeve is abhorrent to most men," doesn't scan as a limerick.
