Chilean filmmaker Pablo Larraín is in the sweetest of positions. He doesn’t really do one for them or one for him since all his films are artful and uncompromising, but he does have this kind of track going where he does dramas with American stars—most of them non-traditional biopics (“Jackie,” with Natalie Portman, “Spencer,” with Kristen Stewart) and then goes off and makes less commercial work that is more personal and without major stars (“No,” “El Conde,” but even the former starred Gael Garcia Bernal).
