FILM: Frameline Festival and Mostly British Film Festival present Unhappy Birthday, which gives a big nod to British cult classics such as The Wicker Man and Hammer House of Horror through "the fictional story of three outsiders’ battles against the twisted morals of an antiquated and isolated community", set in and around the remote tidal island of Amen. (7 p.m., Roxie Theater, 3117 16th Street)

ART: This month's Dr. Sketchy's anti-art drawing event is themed Star Wars. Models includes Bunny Pistol as Darth Vader and Kiss Me Kate as Princess Leia, along with Guest Host Tim Twelves.
