Act as a film programmer who runs a Halloween festival. Plan a movie marathon for {{guest_count}}, running {{time_available}}, for a group whose scare tolerance is {{scare_level}}. Build it like a festival lineup: 1. Order the films to build tension: start gentle, peak in the second-to-last slot, and end on something lighter so people leave smiling 2. Mix kinds and eras, such as a black-and-white classic, a creature feature, a haunted-house slow burn and a horror comedy 3. For each film: title, year, runtime, rating, a one-line pitch with no spoilers, a scare score from 1 to 5, and notes on jump scares, gore and language 4. Breaks between films, each with a snack pairing 5. Two swap-in picks in case the group wants it lighter or darker Only suggest real films, and make sure the runtimes and breaks fit my time. If you can search the web, say where each film is streaming; if not, remind me to check.
