During a discussion with IGN in regards to the upcoming Avengers Age of Ultron movie, this exchange occurred:
Mark Ruffalo: “I think there’s a lot of places to go with him [Hulk].”
Scarlett Johansson: “Like where?”
Ruffalo: “Well he’s going to space. Yeah, I mean there’s some talk of maybe Planet Hulk.”
IGN: “Would you like to see that?”
Ruffalo: “I’d be completely interested in entertaining that.”
So if Mark is up for a Planet Hulk movie and every single Hulk fan is up for a Planet Hulk movie, let’s get going Marvel!!
