25 things we learned on the set of Avengers: Age of Ultron

1. The Science Bros are causing trouble. “Banner’s been living in Stark Tower, and [he and Tony] have been working side by side,” Mark Ruffalo shares. “Banner has his own lab now, he’s doing work that augments Tony’s work, that could lead to a horrible experiment going wrong…”

2. Jeremy Renner’s Hawkeye will have a lot more to do this time out. “We got to do some interesting stuff with Hawkeye which is a different kind of dark,” Whedon teases. “It’s been fun for Jeremy because he was possessed for so long last time – it’s interesting to not be a zombie!”

3. One of the key new relationships will be between Bruce Banner and Natasha Romanoff, who already had a close shave in The Avengers when the Hulk almost ripped her apart. “They’re an unlikely pair, but there’s something about the two of them that neither can deny,” says Whedon, while Ruffalo describes them as “kindred spirits”.

4. As trailers have indicated, there’s dissent in the Avengers ranks too. Where the first film saw them begin divided and gradually come together, Age of Ultron begins with them united and gradually tears them apart thanks to Ultron, Quicksilver and Scarlet Witch’s divide-and-conquer strategising.

5. Much of the Avengers’ problem boils down to their lack of a clear leader post-Winter Soldier. “SHIELD has fallen apart, so this movie becomes Tony Stark and Steve Rogers trying to put the Avengers together without a parental unit like Nick Fury hovering over them,” explains Latcham. “What you realise is that these are guys who work best with rules, and probably do need some adult supervision.”

And as anybody who watched the first film can guess, Tony and Cap aren’t an ideal leadership pairing. “Tony has been paying for everything, designing stuff, building new toys, he’s the benefactor of the whole thing. But Steve Rogers is very much in charge of operations and missions, he’s the moral compass,” Latcham goes on. “But how long can Tony Stark have someone else be in charge?” In other words, groundwork is being distinctly laid for the Stark vs Rogers core of Civil War.

6. Hemsworth found it strange not to be working closely with Tom Hiddleston for the first time. “I was interested to see what was gonna be his conflict or his motivation, because he was sort of driven by that relationship previously. I love working with Tom, and I think there’s always room for more Thor and Loki stuff, but it’s nice to do something completely different.”
