The first trailer for “Josephine,” winner of the top two prizes at this year’s Sundance Film Festival, has been released. Starring Channing Tatum and Gemma Chan, the psychological thriller is a work of autobiographical fiction based on writer-director Beth de Araújo’s lived experiences. Tatum and Chan play parents who struggle to support their eight-year-old daughter, Josephine (newcomer Mason Reeves), after she witness an unimaginably horrific crime in Golden Gate Park. The film also screened in competition at the Berlin International Film Festival. It will continue its festival rollout next month at the Toronto International Film Festival.
