With its stilted visuals and pulpy plot, Little Caesar remains stuck in the stiff, early-sound era, but it's still a prototypical powerhouse, with Edward G. Robinson's titular "Rico" setting the stage for all screen gangsters to follow. The Public Enemy made James Cagney a star (who can forget him smashing a grapefruit into Mae Clarke's face?), and Humphrey Bogart repeats his Broadway success in The Petrified Forest, a stagy adaptation of Robert Sherwood's play, still enjoyable for Bogey's ever-threatening malevolence. Then it's a Cagney triple-threat in Angels (with Pat O'Brien), racketeering in The Roaring Twenties (with Bogart), and especially the jailbird classic White Heat, with a fiery finale and an exit line ("Made it Ma! Top o' the world!") that epitomized Cagney's iconic, tough-guy image. In many ways Cagney was Warner Bros., and this Gangsters Collection pays enduring tribute to him and the important films that forged the studio's rugged reputation. --Jeff Shannon
