The greatness of "Sister Act," and a case for "Sister Act 2"

With the third #TotalSF movie night approaching fast on Dec. 5, the Chronicle's Peter Hartlaub and Heather Knight welcome "Sister Act" superfan and Sisteractivist Sarah Katz-Hyman, who runs the @SisterActivism Twitter account, to talk about the film's greatness. They talk about Whoopi Goldberg's time in San Francisco, and Katz-Hyman makes a case for the underappreciated "Sister Act 2: Back in the Habit." #TotalSF hosts "Sister Act" at 7 p.m. Thursday, Dec. 5, at the Balboa Theatre in S.F. Buy tickets here. Produced by Peter Hartlaub. Music is "The Tide Will Rise" by the Sunset Shipwrecks off their album "Community." Learn more about your ad choices. Visit megaphone.fm/adchoices
