The human race On a day when thousands will race down Broad Street, it's a good time to reflect on running as a mode of transportation. In a remote region of Chihuahua, Mexico, the Tarahumara people call themselves Rarámuri, an Uto-Aztecan word meaning "foot runner," which is how they get around the deep canyons of the Sierra Madre Mountains. Running is so central to their culture that they have traditional 100-mile, daylong races. Though they originally ran barefoot, today they wear homemade sandals made from tires. Annually, they hold a 47-mile ultramarathon in which the Tarahumara race with international runners. Diana Molina's photographs of the Tarahumara are in the exhibition Run! Super Athletes of the Sierra Madre at the University of Pennsylvania Museum of Archaeology and Anthropology, 3260 South St., to Sept. 30. Admission is $12; $10 for seniors; $8 for ages 6 to 17 and students; ages 5 and under free. Call 215-898-4000.

Time travelers Madeleine L'Engle's 1962 novel A Wrinkle in Time is, yes, a timeless classic, in which an awkward teen tries to find her scientist father by traveling the dimensions accompanied by her misfit jock boyfriend and 5-year-old genius brother. It's science fiction, but also a meditation on growing up and the power of love. John Glore's adaptation goes on at 2 and 7 p.m. Sunday at People's Light & Theatre, 39 Conestoga Rd, Malvern, and continues with performances on a varied schedule to May 20. Tickets are $35. Call 610-644-3500.


Above averageThrough his radio show, A Prairie Home Companion, Garrison Keillor has earned a justified reputation as one of America's greatest humorists, with characters such as Guy Noir and faux commercials for Powdermilk Biscuits ("tasty and expeditious"). But listen closely to his tales of Lake Wobegon and you'll come to realize that he is also one of our best writers, with a keen eye for the transcendent amid the quotidian. He tells stories, with musical interludes, at 8 p.m. at the Keswick Theatre, Easton Road and Keswick Avenue, Glenside. Tickets are $59.50 and $69.50. Call 215-572-7650.

The original artists King Vidor's 1928 silent comedy Show People was a vehicle for Marion Davies, protégé and mistress of William Randolph Hearst, the newspaper tycoon (back when there were such things). But the story of a country girl who becomes first a slapstick star and then a dramatic diva shows that Davies was a fine actress who needed no one's help. Made just before the advent of the talkies, it features cameos by silent stars Charlie Chaplin, Douglas Fairbanks, William S. Hart, and John Gilbert. The film screens at 7:30 p.m. at the Bryn Mawr Film Institute, 824 W. Lancaster Ave., Bryn Mawr. Tickets are $10; $7 for seniors and students. Call 610-527-9898.


Being and nothingness The intrepid Andrew's VideoVault presents a typically inventive double bill looking at anomie and angst: Philip Haas' 1993 The Music of Chance, a faithful adaptation of Paul Auster's novel about a drifter who falls in with gamblers and finds himself in increasingly absurd and dangerous circumstances, and Douglas Sirk's 1953 melodrama All I Desire, about an actress who returns to her hometown a decade after she abandoned her friends and family. The films screen at 8 p.m. at the Rotunda, 4014 Walnut St. Admission is free. Call 215-573-3234.

So, not even curator Jay Schwartz knows what will appear on the program Blind Date: 35mm Archival Surprises, since he's never watched them — some of the short subjects, industrial films, and film trailers were selected for title alone. The films screen at International House, 3701 Chestnut St., at 7 p.m. Friday. Tickets are $9; $7 for seniors and students. Call 215-387-5125.
