>>15042499He's likely going the D.W. Griffith route and spending the rest of his career making anti-racism movies like Broken Blossoms and Intolerance to atone for the success and distance himself from the fanbase of his most famous first films with all white casts.
I don't see him abandoning his obsession for accuracy and historical research though So expect his next movie to be set in say pre-contact Africa with an all black cast.
