Michael Aaron Milligan has the profile of a leading actor whose face is familiar even to people who have not seen the films. Whatever else turns up, action runs through the filmography. The career has been built at studio scale rather than at the margins. 'Three Billboards Outside Ebbing, Missouri' is the work that made the name travel, with Pal. 'The Suicide Squad' is the other title with comparable reach. Fame came later than the first credit by a wide margin.
