There are plenty of shows, films, and concerts happening this weekend. Here’s some of what we recommend:

Through Sun 10/21: City Lit Theater proves that even after a century, Ge0rge Bernard Shaw’s Arms and the Man can still bring the laughs. Reader critic Max Maller writes, “Raucous, abrupt, and tightly wound, it deserves as many pairs of eyes on it between now and late October as City Lit can squeeze into its Bryn Mawr black box.” Fri-Sat 7:30 PM, City Lit Theater, 1020 W. Bryn Mawr, 773-293-3682, citylit.org, $32, $27 seniors, $12 students and military.
