The walls of the old Bryce Plantation ooze blood, in creepiest scene from 2004's Evil Remains. This horror film about a slasher wearing the head of a dead dog mostly relies on ridiculous Southern gothic cliches. Allow us to demonstrate.
So Evil Remains is mostly a pretty undistinguished entry in the "young people go out to a deserted plantation to investigate a foreboding legend about an old curse only to die horribly except for a blonde girl" genre, but it does have some pretty great moments of Southern-fried silliness, including the part of the above clip where they insist that the blood coming out of the walls must be "swamp mud" because all these houses are held together by the stuff.
And then we find out, via a character known as Professor Exposition, that actually this house is on the land which was owned by an evil slaveholder who put all her slaves in a torture chamber and her "cruelty knew no bounds." But of course, all of the local plantations are haunted or have a voodoo curse on them, it's the South:
The Civil War-era curse legend gets a major boost in the 1980s, when the Bryce family is living there, and their son Carl strangles a dog to death. The dad gives Carl a good beating, as is only proper, and then the son comes back, wearing the dog's head as a kind of mask, and kills the dad, then sets his mom and himself on fire. Here's part of that scene, which is my favorite moment in the whole film — not least because of the Southern accents that change every few seconds:
Truly a work of genius.
