We're finally getting the star studded first trailer for Matthew Vaughn's spy drama 'Argylle' starring Henry Cavill. We learn that Cavill's Argylle is a fictional super spy dreamed up by introverted writer Elly Conway played by Bryce Dallas Howard. Her life is turned upside down when her new book is a little too close to the truth for some real-life spies who begin to hunt her down.
