Sergio Corbucci(or "The other Sergio", not to be confused with the great master Sergio Leone), was a real movie machine intermittently connected to the conveyor belt of Italian film industry, starting early from the '50s to the late '80s. He made sword-and-sandal(peplum) movies, action movies, police movies, a lot of westerns, dramas, musicals and a lot of comedies. This one is a special eurospy, with a predictable plot: a microfilm (hidden in a tooth pulled out of a dead man's mouth) which everyone wants: the British Intelligence, the Greek police, some Greek villains, some Bulgarian villains and some Albanian villains. The microfilm, as usual, contains names of double agents. There is a "surprise" at the end, we find out that the British agent is also Russian spy... Ty Hardin as Jason and Paola Pitagora as Greta are both OK, natural. Vittorio Caprioli as Pizza, the friend of Jason, is the same Caprioli, here more dramatic than funny. The most convincing is the globe-trotter actor Gordon Mitchell (he also played for Fellini and in a Romanian communist film "Cuibul Salamandrelor"(The Salamander's Nest). He's The Albanian and his look, specially his eyes, are stealing the whole movie.
