This is apparently a short/trailer for a movie pitch which would star Jamie Kennedy as the Granny. In the spirit of Halloween, it is indeed NSFW for being filled with senseless gore and violence. Do enjoy. GRANNY- Short Film/Promo from Steven C Miller on Vimeo.
This is the literal name of the movie and the premise does not steer far from the ridiculousness of it. I’m looking forward to this one.
