Homosexual = evil
One thing that does date the film is the use of homosexuality as a handy metaphor for evil, and a way to turn the audience further against the villains. When we find out Renato Salvatori and one of his co-conspirators are gay, that's all it adds, it seems to me. Actually, Salvatori is such an engaging actor that it made it kind of hot. Costa-Gavras did exactly the same thing in "Compartiment tueurs" ("The Sleeping Car Murders"). Homosexuality is such a shorthand for unprincipled, lawless, uprooted, antisocial ruthlessness in his mind that he employs it as a kind of motivation. If guys will do THAT, they'll do ANYTHING.
