Safe assumption lol. His corruption surprised me more than anything else in the movie. I thought Zola's return was great (not sure how people thought he was MODOK, but okay), they definitely made him and Hydra in general much scarier than they were in the first flick.
I dunno if they should bring Red Skull back, not sure he could get much deader than what happened to him in the last movie lol. Much as I love Christoph Waltz though, I'm not sure he'd be great as RS. I'm sure he could pull it off acting wise, but don't think he has the right shaped face for it. Also, for those that haven't scene it yet, we get a quick but nice close up of Scarlett Johansson's belly button (unless they used a stunt belly for whatever reason, but this was filmed well before she got pregnant, so I can't imagine why it wouldn't be her).
To keep this on topic of TV shows though, anyone else watch the season premier for Game of Thrones? Pretty solid first episode, but the scene at the end with Arya and the Hound was amazing, best part by far for me :D
