Sunday Happenings

Rock and Roll Yard Sales

-- Tropical storms can't stop the rock, but they can delay it by a day. Pick through the corpse of rock and roll at the Rock and Roll Yard Sale, which features hipster duds, LP records, and other nostalgia items. Unlike competing yard sales, this one starts in the afternoon. Rock on. Union Square Plaza, Somerville, 3 p.m. Free.

Martial Arts Flicks

-- Also pushed back by Hanna, the screening of Red Heroine, a 1929 silent Chinese martial arts flick, accompanied by a live soundtrack provided by Devil Music Ensemble. Union Square Plaza, Somerville, 8 p.m. Free.

The Animals

-- The MSPCA-Angell Walk for Animals is a fundraiser for the nonprofit veterinary hospital, which relies entirely upon private donations. Boston Common, 11 a.m. $25 registration.

Tough Guys

-- The Harvard Film Archive is the only place in greater Boston to see Randolph Scott, Joel McCrea, Steve McQueen, Robert Preston, James Coburn, and James Mason all in an afternoon and evening. It's tough guy day at the Peckinpah
retrospective, featuring Ride the High Country, Junior Bonner, and Cross of Iron. Harvard Film Archive, 24 Quincy St., Cambridge. More information.
