Check out this claymation horror short film by Michael Granberry! It's based on the H.P. Lovecraft story "From Beyond."
I really like the creepy animated style of this piece. It certainly has the right feel for a Lovecraft film.
Synopsis from IMDB:
An unsuspecting man falls into an otherworldly trap set by a psychotic genius in this spine-tingling animated film based on the short story by H.P.Lovecraft.
