Simon Says (2006)

Eccentric genius Crispin Glover stars in a dual role as twin brothers Simon and Stanley in the fright flick Simon Says (2006). When Simon and Stanley come across a group of college buddies spending a weekend partying on the lake, the gruesome twosome decides to brutally murder the whole gang. Amidst all the splatter, we get some very brief skin from Carrie Finklea. Simon says, “Put more nudity in the sequel.”
