In the stratosphere of cinephiles, the anticipation for a new David Fincher film is palpable. Unveiled by Netflix before a crowd of film critics and journalists on Thursday night, his 11th feature film “Mank” is both personal and technically proficient. It’s been a decade since Fincher received a nomination for best director for “The Social Network,” a loss that still resonates with many awards enthusiasts today. With “Mank,” he’ll most likely pick up another nomination in the category.
