'The Old Guard' Dir. Gina Prince-Bythewood

"Female characters are not [usually] the center of the story," filmmaker Gina Prince-Bythewood says. Her new movie, 'The Old Guard,' follows a diverse group of world-weary warriors who've been alive for centuries. Prince-Bythewood also talks about choreographing fight scenes, and her other films 'Love & Basketball' and 'Beyond the Lights.'
