Aretha’s no Mavis! The declaration gets a laugh in Jessica Edwards’ documentary Mavis! on HBO. Last week’s premiere screening at the Alliance Francais, was the film party of the season: inspiring at 76, Mavis Staple is a dynamo. When Edwards heard her perform at the band shell in Brooklyn’s Prospect Park, she knew she had to make a film about her. Mavis Staples started making gospel 65 years ago with her family, The Staples Singers. She’s influenced Bonnie Raitt, Prince, Wilco’s Jeff Tweedy, and Bob Dylan, who, as a young folksinger when they used to tour together, asked her dad for her hand in marriage. “You’d better talk to Mavis,” he said.
