All of the Tod Slaughter films are pretty much variations on a theme: lustful, socially respected Slaughter (rubbing his hands together and cackling with glee and generally acting like Snidley Whiplash) tries to woo the daughter of a kindly man in finacial straights by hold a mortage or a loan over their heads. He's never opposed to polishing off a few revials, usually laughing hysterically as he does so. THE CRIMES OF STEPHEN HAWKE varies a bit from that and is probably the least interesting of the ones I've seen. Granted all of them were hopelessly old-fashioned even when they were made. Several of them even poke fun at themselves for being old-fashioned with prologues, like you mentioned THE CRIMES OF STEPHEN HAWKE does.
None of the Slaughter are what you'd call good films, but I think several are a lot more fun.
SWEENEY TODD: THE DEMON BARBER OF FLEET STREET The Sondheim musical version is currently being filmed by Tim Burton with Johnny Depp, Helena Bohnam Carter, and Sasha Baron Cohen
THE MURDER IN THE RED BARN This has a surprising "unwed mother" subplot. Based on a true story!
THE FACE IN THE WINDOW Feature a werewolf-like creature, with some odd sci-fi elements
I think these are a bit more entertaining than HAWKES, with Slaughter at his hand-rubbing, cackling, conniving best.
Also: all are only about one hour long.
An amusing aspect of all of Slaughter's films is they are so rushed he comes across as a most unsuccessful villian, going into his "Curses! Foiled again!" routine at the fist sign of trouble.
Slaughter's films are definitely not for most modern tastes, but I think they're a hoot. As a matter of fact this thread prompted me to rewatch IT'S NEVER TOO LATE TO MEND when I came in from doing yard work this afternoon! Plot: Slaughter indulges in some gleeful torture of inmates as the Squire in charge of the county jail, while leering after the daughter of a finacially troubled farmer.
