Peter Debruge Chief Film CriticThese days, it’s refreshing to speak with someone like Mike Leigh whose vocabulary hasn’t been corrupted by the latest Hollywood trends. For example, when Leigh uses the word “content,” it’s doesn’t mean the same thing as 98% of his peers, for whom the term has come to describe the swill that fills the various streamers’ pipelines.For Leigh, “content” refers to the substance of a film or play, as I found when asking Leigh, who is the subject of a 14-film, career-spanning retrospective by New York’s Film at Lincoln Center — from “Bleak Moments” to “Peterloo,” with two shorts thrown in for good measure — where he thinks audiences unfamiliar with his work ought to begin.
