It's practically become a custom for modern spy movies to incorporate the plot thread of a normal person (typically the lead character) getting wrapped up in spy shenanigans to sometimes humorous, other times dramatic, effect. Just look at offerings from 2010 onward like Cars 2, Killers, Bridge Of Spies, Argo, Abduction and (kinda) Salt. It's easy to see why this storytelling device is utilized frequently since it allows for the lead character to engage in high-concept spy going-ons while also being the type of everyday individual the audience can immediately relate to. Perhaps Alfred Hitchcock could be considered a "hipster" in this one case, since he was utilizing that plot scenario "before it was cool" way back in 1959 with his (rightfully) acclaimed motion picture North By Northwest.
