FILM: Brando sings in Guys and Dolls at 2:15 and 7:00. And at 5:00 and 9:45, catch the 1944 film The Princess and the Pirate, starring Bob Hope as a hapless actor who gets caught on a high seas adventure with a runaway princess. Oh, Bob.

ART: The Artist-Xchange is opening their December show tonight. The gallery features up-and-coming local artists and sells works on a consignment basis. If, however, you are not in the market for an accent piece for the foyer, there will also be music by DJ Yoko and a free coffee tasting by Weavers coffee. The exhibit runs through the end of the month.

7-10pm // Artist-Xchange (3169 16th Street) // free

CLUB: Get your dubstep on for the Polaris event at Mezzanine tonight, where the guest DJ, Max Ulis, comes from Canada, eh. One tenth of the proceeds of Polaris will be contributed to Green For All, which means if you forget to compost, you can just order another drink and call it a wash.

10pm // Mezzanine (444 Jessie St) // $20, $15 before 11pm
