The Man From U.N.C.L.E. is unexceptional but rather fun, in a slightly leaden way. Guy Ritchie directs the action well, attempts a cheeky ironic tone for the film he doesn’t always succeed in achieving, and is not very good with those actors who need his help: Armie Hammer is completely inexpressive physically though does a great accent and can find comic timing vocally that somehow eludes other aspects of his performance; Henry Cavill does better and is better looking doing it but he’s done so much weightlifting his body strains at his suits, evoking a kind of physical boxiness that works against that nonchalant physical elegance the character is meant to exude; a rare instance in which a great body works against the role (though his performance is also sabotaged by the cinematography); Alicia Vikander is pretty but can’t find a rhythm for her performance and seems wasted; Elizabeth Debicki fares better as the villainess and her long leggy frame, elegant way of wearing clothes, and understated ironic way with a line makes her very enjoyable to watch. But it is Hugh Grant — only in the film for what seems like two minutes — who steals the show. A trifle, not light or sparkly enough but with some clever action and a great score of 60s tunes. The audience did like it even though either the print or the projection didn’t provide the luminosity the colour palette seemed to require. It is better and more enjoyable than an episode of the old TV show.
Addendum: I have now seen this twice more on Netflix and found it great fun. My appreciation of Armie Hammer and Alicia Vikander increased; my love of the soundtrack sky-rocketed. It is a trifle, very broad and fast-moving with the set-pieces working much better than my first impression. I now recommend it.
