The opening sequence of director Guy Ritchie’s “Man from U.N.C.L.E.” is promising — a clever, action-filled chase through East Berlin as American agent Napoleon Solo (Henry Cavill) attempts to get his cool and quippy self and Alicia Vikander (Gaby Teller) into the safety of West Berlin. Hot on their heels is Russian KGB agent Illya Kuryakin (Armie Hammer), whose bulk and brooding determination is its own kind of super power. Both men are exceptionally capable and cucumber-cool under pressure, and anyone familiar with the source material (which may not be too many of you considering the television show was cancelled almost 50 years ago) knows that Solo and Kuryakin are destined to become unlikely American and Russian superspy-partners. Unlikely because the year is 1963 and the war is cold. As I said, the opening is promising, which means it is not great, and yet it is still the best part
