Plot: In 1963, American spy Napoleon Solo (Henry Cavill) and Soviet spy Illya Kuryakin (Armie Hammer) need to find a nuclear scientist to preventing him from selling bomb-making secrets. They track down his daughter Gaby (Alicia Vikander) in Berlin and go together to Italy. All the while Illya and Solo are in a constant rivalry. They crash a ritzy party, break into a secret lab, and almost drown in a harbor. In they end, their governments decide they need to work together to make a sequel. [imdb] [photos]
An example of the tone is when Illya was driving a boat in the harbor and being chased by bad guys in another boat. Solo casually steals and eats someone's lunch while the chase scene goes in and out of view in the window over his shoulder.
Director Richie spends time developing the characters. Illya is a little crazy, and can go out-of-control. Solo is into clothes and art theft.
Don't look for any messages or moralizing. Solo is a thief on the side, and they run up a high body count. They don't kill each other, so friendship rules to that extent.
