The Lady from Shanghai (Orson Welles, 1947). Where is that line between the too-much-ness of Welles as actor and the hamminess? To put it another way: between the actor caring too much and not caring enough? You can say (David Thomson does) that Welles put a lifetime of acting into Citizen Kane and everything after was a variation on parts of Kane’s corruption. And everything is informed for us now by biography. The unconvincing figure Welles plays here, the Irishman O’Hara, is smart but clueless, an insightful writer who is easily duped. Welles’ expressionist flourishes are daringly at work in the closing amusement park Caligari scene, despite studio edits, but I’m as taken with the hallucinatory aquarium scene. No one has ever made sense of the story.
