Saturday night’s special guest Camilla Fox will speak on her founding role in Marin’s Project Coyote and the group’s mission of coexistence. The film fest takes place on Saturday and Sunday, Jan. 23–24, at the Marin Humane Society, 171 Bel Marin Keys Blvd., Novato. Saturday, 7pm; Sunday, 1pm. $15–$20. 415.883.4621.
