Ha! Castle Freak... I'm amazed anyone even remembers that movie. Its the third Stuart Gordon movie (loosely) based off the works of H.P. Lovecraft and staring Jeffrey Combs and Barbara Crampton. They were... well entertaining. And Jeffrey Combs was awesome in those, especially the Re-Animator one. Incidentally, this reminds me that I've previously claimed Chris could pass for some sort of unspeakable Lovecraftian horror. What do you guys think? A Ghoul? Mi-Go? Deep One? One of the inbred Martenses? Even dread Cthulhu himself? Or Azathoth, the Blind Idiot God?
Personally, I'm leaning towards the Martenses, because they live in a hoarder house (well, mansion, but the Lurking Fear describes their home as having degenerated to the level of 14 Branchland Court, pre- or post-fire), they're an inbred old New Amsterdam family (much as Chris claims convoluted little genealogy goes back to Anne Boleyn, but undoubtedly snakes back over into itself a few times...), and they've reverted to a feral state (exactly like Barb and Chris). More importantly, they also possess Chris' much vaunted heterochromia... thanks to inbreeding incidentally.
