I'm a huge fan of "The Man From U.N.C.L.E.", both the classic TV-show and the movies. None of the U.N.C.L.E. movies are bad, but there's a couple of them which could have been a lot better. For example the last movie "How to Steal the World (1968)" which was basically just a couple of TV-episodes thrown together. It was terribly unfunny and the Robert Vaughn and David McCallum just seem embarrassed to be there. Then there's "Karate Killers, The (1967)" which was one of the funniest but with a very weak plot, it seemed as though they came up with a plot in five minutes which was merely content with laughable scenes and quirky situations.
"Spy in the Green Hat, The (1966)" on the other hand, is both exciting AND funny. Especially the scene where Napoleon Solo (Robert Vaughn) hides from THRUSH agents under a young woman's (the incredibly cute Letícia Román) bed and is caught by the woman's grandmother (Penny Santon), who is forcing Solo to marry the young woman. He successfully escapes, but is hunted by a legion of stereotyped Italian gangsters. Now that's comedy.
All the actors, including among others Janet Leigh and Jack Palance, give wonderful perfomances. Particularly Palance who probably is the only actor in the movie business who can overact in a good way.
The 60's in a nutshell, don't miss it for the world.
