Frank Sinatra is cool and very natural (he also produced the film). Virna Lisi is also cool and of rare beauty. Richard Conte is cool. Same Alf Kjellin, known from all the famous TV series. Anthony Franciosa is not cool, but so does the role. Good music by Duke Ellington. Great cinematography by William H. Daniels. Very original story! So many attributes make viewing imperative.
