Sometimes, one minute of careful editing, brilliant acting, and music tells you everything you need to know about a character in a film. This is the infamous entrance of Robert DeNiro’s character Johnny Boy in Martin Scorsese’s breakout film from 1973 “Mean Streets.” The scene is cut to the Rolling Stones’ “Jumpin’ Jack Flash” and Johnny Boy enters the club, two girls on his arm, acting like a cocky jackass with a stupid hat and suit. His friend, played by Harvey Keitel, eyes him with the most in-control “Oh s–t! This a–hole better not start anything tonight” look I’ve ever seen.
