October Movie Nights brings a spooky outdoor movie series to Main Street Garden in Dallas, with five Friday nights of horror, camp and supernatural classics. It's a Halloween countdown that spans four decades of cinema, from a witchy 1990 favorite to Buffy the Vampire Slayer and beyond. Movie nights in a downtown garden are an easy, laid-back way to get into the Halloween mood. It's free and family-friendly, and it's pet-friendly too.
