Tonight is opening night for the Mill Valley Film Festival: the biggest Bay Area film fest of the year. Among the films showing is Sweet Dreams, the story of a group of Rwandan women who found community and support after the 1994 Rwandan genocide by coming together as a drum troupe. The film was codirected, coedited, and coproduced by Rob Fruchtman and his sister: Berkeley resident Lisa Fruchtman. KALW’s Ben Trefny spoke with Lisa Fruchtman about the making of Sweet Dreams.
