Three adult children are forced to live at home with their deranged parents in Dogtooth, a surreal Greek film directed by Yorgos Lanthimos. According to the storyline, “A child is ready to leave the house when the dogtooth comes out. Only then is your body ready to face the dangers that lurk outside.” Permanently grounded, the children are taught bizarre lessons (a “zombie” is a small yellow flower, a “pussy” is a large lamp, etc.) and behavioral patterns, including how to protect themselves from cats (“the most dangerous animal there is”) by dropping down on all fours and barking like dogs. $5 for non-members, 6:30pm, the McNay’s Chiego Lecture Hall, 6000 N. New Braunfels, (210) 824-5368, mcnayart.org.
