Mark Ruffalo Promises More Science Bros Stuff In Avengers: Age Of Ultron

In a new video released by Total Film, Mark Ruffalo walks viewers through his entire career in just four minutes, from In the Cut to the still filming Avengers: Age of Ultron.

While the first Avengers movie gets passed over, Ruffalo did have a bit to say about his return as the Hulk in Avengers: Age of Ultron.

It's, oddly enough, a much bigger movie than Avengers 1 was. It's a little bit darker. It's…we get a lot deeper into the character now, since we established them in the first one, so we get to cover a lot more ground. Ultron's incredible. There's more stuff with Banner and Tony Stark, more "Science Bros" stuff. And it's pretty sweeping, it's pretty epic.

Bruce Banner and Tony Stark's "Science Bros." relationship was one of the most popular parts of the original Avengers, sparking memes and fan fiction, so many fans should be happy to hear that they'll get more of it. Meanwhile, Ruffalo's comments about the film being "darker" echo those of director Joss Whedon.

Avengers: Age of Ultron comes to theaters May 1, 2015.
