It may not have The Public Enemy's eye for composition or the nihilism of Howard Hawks' Scarface, but Mervyn LeRoy's Little Caesar is still the archetypal Warner Bros. gangster flick of the '30s. He had several great turns after this (Double Indemnity, Key Largo), but Edward G. Robinson will always be best known as Rico. You've seen the rise and fall of the ambitious hood, but Robinson's career performance adds the kind of gravitas that so many of Little Caesar's readymade successors lacked. And the ending has one of the most memorable quotes in Hollywood history.
