For those wondering what Kevin Smith's entry into the horror genre might look like, your answer has come in the form of a teaser poster for the film, and that answer is: classic. REAL classic. As in, ghost-represented-by-someone-draped-in-a-sheet classic, apparently.
Nothing to do now but wait and see what hilariousness the Scary Movie franchise is going to pull out of this. A sheet ghost with no eye-holes running into things? Sheet ghost wearing the Scream mask for some reason? Sheet ghost chasing Scream guy, and then the sheet gets caught on something and yanked off, revealing an actress who looks similar-enough to Lindsay Lohan underneath, who then gets immediately arrested? Yup, that's the one.
