A gem of an international heist thriller courtesy of Giuliano Montaldo (SACCO AND VANZETTI) is first rate stuff. A retired professor (Edward G. Robinson) asks the assistance of his childhood friend (Adolfo Celi THUNDERBALL), now a crime lord, in requisitioning four professional criminals (Klaus Kinski, Robert Hoffman, George Rigaud, Riccardo Cucciolla), each with their own specialty, in pulling a theft of 10 million dollars worth of diamonds. An uptight “plain” secretary (Janet Leigh in glasses) literally holds the key to the theft’s success. The robbery is beautifully played out with the requisite tension and a marvelous twist at the end. Unfortunately, Ennio Morricone’s score comes off as hastily put together.
