If you've seen any of the prequel movies to The Avengers, then you probably know Clark Cregg as the wisecracking S.H.I.E.L.D. agent Coulson. In the new movie, he's joined by fellow agent Maria Hill, played by How I Met Your Mother's Cobie Smulders. I sat down with the pair at the film's recent press day to talk about the film's amazing special effects, what it was like for Smulders to join the cast as a newbie, and more. Watch!
