Interested in being severely spooked this pre-Halloween weekend? Look no further than the Coolidge Corner Theater’s 13th Annual Halloween Horror Movie Marathon. Kicking off at 11:59 PM on Saturday night with Alfred Hitchcock’s Psycho and the original Texas Chainsaw Massacre, this marathon goes on for 12 straight hours. The rest of the movie lineup is a surprise but fear not, you will be scared straight. Tickets for the double feature of Psycho and The Texas Chainsaw Massacre are $15. If you want tickets for the entire 12-hour marathon, it’s only an additional $5. Stumble out of the theater into the cold light of day on Sunday afternoon and enjoy one of Coolidge Corner’s many excellent restaurants. Check out the original 1960 Psycho trailer below.
