From Istanbul, Orders to Kill

From Istanbul, Orders to Kill (1965) is a action directed by Carlo Ferrero rated 10.0/10.

A starving writer is offered $20,000 by an old friend in the intelligence service to pose as “Felix,” an international smuggler, because the writer looks exactly like this Felix. There’s lots of action, beautiful locations in Italy and (presumably) Istanbul, double-crosses galore, fistfights and chases, etc.
