Kingsman was the action spy comedy we didn't know we needed in 2014! Matthew Vaughn's adaptation of Mark Millar's comic series, The Secret Service, took theaters by storm, made Taron Egerton a star, Colin Firth an action hero and even spawned a few sequels with The Golden Circle in 2017 and The Kings Man in (hopefully!) 2020. But how close did Vaughn and co stay to Millar's original vision of The Secret Service? It's time to ask, What's the Difference?
