CANADIAN QUIDDITCH CUP (FREE!)
The final movie has come and gone, but it’s still possible to get your Potter fix. While they won’t be flying around on Nimbus 2000s, Carleton University plays host to more than 100 muggles for the first-ever Canadian Quidditch Cup. The non-flight version of Quidditch, which still involves broomsticks, is a modified version of the sport that mixes rugby, dodge ball, and tag. Eight teams will battle it out to decide who gets to go to the Quidditch World Cup tournament in New York City in November. Come cheer for Carleton, ranked second behind McGill. 9 a.m. to 5 p.m. Saturday, Oct. 29. from 9 a.m. to 5 p.m. Check it out on campus at the Ravens’ Road Field. Map of campus can be found here.

WHISPERING PINES (AND PINTS!)
It’s a world premiere! In the divided city of Berlin in 1987, live Renate and Bruno, artists who want to make a new world. When Thomas, a Canadian academic, arrives on their doorstep bearing gifts from the West and dreams of life beyond the Wall, their lives are turned upside down. Years later, in a peaceful cabin on the shores of Lake Superior, the three come together one last time to confront the betrayal that tore them apart. Politics, intrigue, and the cold war. Sounds like the makings for a great play. And, bonus!, on the opening night (Friday, Oct. 28), the German Embassy has partnered with GCTC for Whispering Pints (geddit?). Stop by after the show (10 p.m. to 1 a.m.) for German beer, food, and music. Cover charge is $5. The play runs Friday, Oct. 28 to Sunday, Nov. 13. Tickets are $45 (adult) and $34 (students and seniors). 1227 Wellington St. W., 613-236-5196, www.gctc.ca.
