Castle Freak

This infamous straight-to-video Stuart Gordon film stars Jeffrey Combs, Barbara Crampton, a castle, and a freak. While this is nominally a loose adaptation of "The Outsider", it mostly ends up being a gory and horny slasher film. And that's fine! But it's not without a brain or a heart, because just under the surface is Gordon's reaction to Lovecraft's conflicts about whether nature or nurture decide a person's fate.
