There has never been an actor as obsessive as Day-Lewis. He dons the role as if it were a handmade suit. He is a champion of stillness and he seems, like certain rare sportsmen, to be preternaturally blessed with time—enough time, that is, to take stock of a situation, while people bustle around him, and to ponder his next move. His thoughts look more dramatic than other actors’ deeds, and his deeds are done with a deliberated grace. If it is true, as Day-Lewis has declared, that “Phantom Thread” will be his final movie, we will miss him when he retires from the game that he has crowned.
