“I was talking to Robert Downey the other day, and he said, ‘Ruffalo! I heard you’re coming out here,’ and I said, ‘OK! I’ll be there,’” Ruffalo said, when asked whether he would appear in the film. The actor said he has not read the script of “Captain America: Civil War,” but hopes to join the cast anyway.

Ruffalo said he relishes the experience of Marvel films. “I like the cultural significance of it, as an art project. It’s crossing into all kinds of cultures and belief systems and ideologies. It’s hitting a lot of boxes, and really specialized boxes, too. And ultimately, the messaging of it is pretty good,” he said.

Ruffalo’s Hulk was last seen in “Avengers: Age of Ultron.” He was seen going on a rampage after Wanda Maximoff manipulated his mind. Robert Downey Jr.’s Tony Stark/Iron Man stops him with his anti-Hulk armor.
