[Sebastian]’s really got into it. He’s read all the comics already and spent the last year prepping by just immersing himself in Cold War history, to the point where he would comment on some of the stuff about the origin of the Winter Soldier that I put in the comic. He’d say, ‘Did you know that there really was a General assassinated back then?’ and I’d say, ‘Yes, that’s what I based it on - I took actual moments of history and put him into them.’ He was so into the ride and you couldn’t ask for more.
