The Enforcer (1951)

A crusading district attorney (Humphrey Bogart), out to convict the head of a vicious murder for hire ring, must race against time to find the evidence he needs to bring down the mob boss (Everett Sloane). Directed by Bretaigne Windust (JUNE BRIDE) with an uncredited assist from Raoul Walsh (WHITE HEAT). This early example of what has come to be known as a police procedural is also considered film noir although I wouldn't consider it so myself. The film is often tedious and repetitive with what seems the same scene played over and over again, only with different characters. The movie opens in the present and goes into flashback mode where there are several flashbacks within that flashback. There is a very nice twist at the very end which ends in an intense race against time in order to prevent another death. It's a good little suspense flick, you'll just have to endure the frequent monotony to get to the excellent payoff. With Zero Mostel, Ted De Corsia, Susan Cabot, Roy Roberts, Michael Tolan, Don Beddoe and Patricia Joiner.
