A horror classic that made audiences hurl, as well as reports of heart attacks and miscarriages, “The Exorcist” holds up for several reasons: creepy story, gnarly special effects, spooky-ass music, and its most controversial scene, which allegedly gave the band Red Kross its name, is still controversial today. In 1973, how the hell did that make it into a film? Some critics speculated the movie was too expensive to get an X-rating. 7:15 p.m. $6. byrdtheatre.org.
