Plot and characters

The story centers on Louis Strago (Jack Palance), a T.H.R.U.S.H. chieftain who recruits the ex-Nazi scientist Heinrich von Kronen (Ludwig Donath) to reroute the Gulf Stream, transforming Greenland into a tropical base for T.H.R.U.S.H. while cities such as New York and London are put "in the deep freeze."⁸^•⁶ Janet Leigh plays Strago's secretary, Miss Diketon, described in the episode guide as his deadly secretary in an over-the-top performance.⁶

The plot also draws in the Stiletto Brothers, three retired Chicago gangsters played by Eduardo Ciannelli (Arturo "Fingers"), Allen Jenkins (Enzo "Pretty"), and Jack La Rue (Federico "Feet"), with Joan Blondell as Mrs. "Fingers" Stilletto. They come out of retirement to help their niece from Sicily track down Solo, whom they force toward a shotgun wedding before joining the agents against T.H.R.U.S.H.⁹^•⁵ Edward G. Robinson was reportedly the first choice to play Strago before Palance took the part; the character is nervous and obsessive about cleanliness rather than a typical tough guy.⁶

Title and television source

The film's title points to a minor character. Will Kuluva, who plays a T.H.R.U.S.H. official named Mr. Thaler near the end of the picture, wears the green hat of the title in a very brief appearance.⁷ Kuluva had a history with the series: he originally played the chief of U.N.C.L.E. in the pilot, The Vulcan Affair (1964), which was re-edited into the theatrical feature To Trap a Spy.¹

The two source episodes were the eleventh and twelfth of the third season, with production numbers 8433 and 8434.³ The conversion of two-part episodes into theatrical features was routine for the series in the 1960s, motivated partly by the name value of the guest stars that the two-parters could afford.⁴^•⁸

Production and release

The theatrical version was intended mainly for international audiences. According to one retrospective account, it was not released theatrically in the United States, just abroad, with added sex and violence relative to the broadcast episodes.¹⁰ IMDb records a release date of March 3, 1967 in Ireland, and the film circulated in Germany as Der Mann im grünen Hut and in France as L'Espion au chapeau vert.¹^•¹¹ Filming locations included Pacific Ocean Park in Santa Monica, California, standing in for the Sicilian setting.¹^•¹²

Boris Ingster produced; Fred J. Koenekamp was the cinematographer, Nelson Riddle wrote the score, and Jerry Goldsmith's Man from U.N.C.L.E. theme appears in the music.⁷

Reception

The film holds a 5.8/10 rating on IMDb from about 667 users.¹ On Rotten Tomatoes it has no critic reviews on the Tomatometer and fewer than 50 audience ratings.¹³

A contemporary review in the New Zealand Listener (June 30, 1967) complained that the dialogue left the principals looking ill at ease but singled out the Stiletto Brothers sequence, in which director Joseph Sargent "contrives some genuinely comic byplay," most rewardingly when the three uncles, having uncovered a nest of T.H.R.U.S.H., toy with the idea of staging another St Valentine's Day massacre.⁹ Later reviewers have described the film as sitting between action film and satire, with Jonathan Lewis, reviewing for Mystery*File, calling it a light, entertaining 1960s spy film whose title has almost nothing to do with the movie beyond the character in the final scene.⁴ A 2022 review judged the film more madcap than its predecessors, praising Sargent's touches such as a fight in slow motion or freeze frame while noting the expanded risqué material added for the theatrical cut.¹⁰

The film remains available commercially in the United States, where it can be rented or bought on Amazon Video, the Apple TV Store, and Fandango At Home.⁵
