A great many 1930s British horrors are lost, most of the decade's output, in fact. Virtually none of the "Quota Quickie" horrors exist, and even notable productions like CONDEMNED TO DEATH, THARK and (IIRC) THE MAN IN THE MIRROR are gone. Even THE GHOUL was lost until the late 60s, when a print supposedly turned up in a woodshed on the Pinewood lot.
