“Long a staple of television, the technique has gained traction in recent years as an antidote to the kind of smash-cut film editing that first became popular in the ’90s before passing into cliché. But the execution of extreme close-ups requires a certain bravery on the part of actors: nary a blemish, a crow’s-foot wrinkle, or clogged pore will be spared the camera’s unblinking scrutiny.” Thank heaven for CGI.
