‘Martin Lawrence You So Crazy’

This 1994 performance film, fluidly directed by Thomas Schlamme, finds Lawrence almost always in-your-face raunchy and scatological, an enthusiastic dispenser of profanity whose explicit detailing of all kinds of sexual situations led to “Crazy” getting an NC-17 rating and a change of distributors. But Lawrence is more than someone who talks dirty. As this film of a Brooklyn Academy of Music concert shows, he is an alive comic presence, an adept social commentator, and, most surprising, a promoter of values that can only be called mainstream. Like Richard Pryor, Lawrence really doesn’t deliver jokes; he tells stories, dispenses advice and describes outrageous situations. His routines are offshoots of the kind of no-holds-barred frankness that always characterizes street humor. “You So Crazy’s” lack of boundaries will unnerve people who think they’re beyond all of that. Which is no doubt part of the point (HBO Saturday at 9:40 p.m.).
