The setting of David Fincher’s Mank largely resides in the confines of Herman J. Mankiewicz’s bedroom and its surrounding desert vistas. The man who is about to pen what many consider the bible for the greatest film ever made was sent there—banished, really—by Orson Welles in order to keep a low-profile from the Hollywood press, and to keep “Mank” out of boozy trouble. Thus his North Verde ranch is a location of moody interiors and desolate skies, and it’s framed by Fincher with the kind of reverence one might expect for an actual bible.
