He'd have to beat not just Alex Guiness and Terrence Stamp, but now Max von Sydow, on top of Liam Neeson, Ewan McGregor, Natalie Portman, etc. I've heard Marriage Story is excellent, but is it a Bridge over the River Kwai, Kind Hearts and Coronets, or Seventh Seal? What's remarkable is how wooden the Star Wars performances are by some of its better actors (Portman, Oscar Isaac, etc.).
