Humorous Halloween horror is on the menu when BATS Improv fills your trick-or-treat bag with bite-size fiendish tales during Fright Day-Night at Fort Mason Center for Arts & Culture. Get ready for a frightfully delicious night when BATS digs up a surprise guest “Master of Scare-a-monies” from a secret hiding place to host the spook-tacular improvised anthology, just in time for Halloween.

Join the eerily talented Main Stage Company for an evening of thrills, chills, and dark fantasies when the moonlight glows, alley cats yowl, spiders weave sinister webs, skeletons rattle, and cackling witches, bats, and ghosts fill the air. BATS players are inspired by many evil elements — films like The Exorcist, Invasion of the Body Snatchers, Night Of The Living Dead, Dracula, and other spooky movies. BATS welcome audience suggestions of creepy ideas to bring the undead to life on stage for a Halloween festival of unspeakable improv horror.
