Dozens of big stars have joined the Marvel Cinematic Universe and bonded together as a cast over the years.

Still, there is undeniable chemistry between them.

He went on to say that he was still hesitant about taking the role even after director Joss Whedon told him he was "the right person."
"And then I got a call from Downey, it must've made it to him that I was ... hemming and hawing, and he just simply said, 'Ruffalo, let's go. We got this,' in true Iron Man fashion," Ruffalo said. "And then after that, I was like, 'I guess I have to do it.'"

Ruffalo tweeted that his costar is "as solid a man there is" and that the discussion was a "distraction."
