Social climbers

The Reel Rock Film Tour, a traveling showcase of extreme climbing footage, stops in Arlington tonight. It's basically a chance for you to see people hanging off mountains and icy Arctic walls. Better them than you, right? These stories of daring climbs look brilliant on the big screen, and if you're into the outdoors, you're bound to meet some other hiker types at the event. Tour sponsors include the North Face, so you may also walk away with some good climbing swag. 8 p.m. $15. Regent Theatre, 7 Medford St., Arlington, 781-646-4849. www.regenttheatre.com

ALSO TONIGHT: Boston Ballet opens "Cinderella," and the Nora Theatre Company opens "Martha Mitchell Calling."
