In a Deadline interview, SNL’s actor Bill Hader talk a little about ‘The Disappearance of Eleanor Rigby‘. Check it:
It’s two movies. This guy Ned Benson wrote and directed it. James McAvoy and Jessica Chastain have this tragedy happen, so in the His version, it’s from McAvoy’s point of view, and you see how he’s dealing with this tragedy. It’s all shot in steadicam and cold colors and stylistically and Her is stylistically much warmer. But you’ll see scenes in both movies, but we would shoot the His version one way, and the Her version another. We would change wardrobe and shoot the same exact scene and approximate dialogue so she remembered it in a different way, but the same information is put across (to the audience).
