How can you tell same director made another movie?

I think most directors that have a unique/distinct visual style, if I'm reasonably familiar with them I can for the most part be able to tell if a film is by them or not.

I can tell an Ozu film for example, due the framing, camera position, lack of camera movement, editing style, actors used, thematic and narrative concerns.

Someone I'm less familiar with, I'd have trouble with even if their style is quite distinct.
