We already knew that “Challengers,” starring Zendaya, was pulled from Venice opening night. A report also stated that Bradley Cooper wouldn’t be going to promote “Maestro,” but the festival took another hit this morning. In an Italian interview, Venice Director Alberto Barbera says that Emma Stone (“Poor Things”) and Michael Fassbender (“The Killer”) will not be attending Venice either. No stars, no problem. Let the films speak for themselves.
