A less good-looking Terrence Stamp in William Wyler‘s The Collector with three captives, 23 separate personalities and a shaved head. James McAvoy is the kidnapper, white-haired Betty Buckley is his psychiatrist, and The Witch‘s Anya Taylor-Joy is the most noteworthy of the three victims. It’s called Split, and it opens on 1.20.17 — the second day of the 2017 Sundance Film Festival.
