Creator Joel Hodgson and the original cast of the award-winning cult television show MST3K return for more movie riffing in front a live audience. The focus is on the terrible 1976 horror film Rattlers, in which a chauvinist herpetologist teams up with a feminist war photographer to uncover the mystery behind a spate of killer rattlesnake attacks. This should be explosively, stingingly uproarious, and it’s intended to be something of a Halloween party. Thursday, Oct. 27, at 8 p.m. Lisner Auditorium, The George Washington University, 730 21st St. NW. Tickets are $25 to $35. Call 202-994-6800 or visit lisner.org.
