Mark Rufalo teases fans about Hulk’s involvement in Avengers: Age of Ultron

Over the year, fans have been constantly teased about how Tony Star, aka Iron Man, appears to be regretting on creating Ultron but recently Mark Ruffalo breaks his silence as he teases fans on how his character also plays a part in the creation of the highly-intelligent robot.

Ruffalo plays Dr. Bruce Banner, the human and mild-manner alter-ego of The Incredible Hulk.

According to his interview with Total Film Magazine, "Banner's been living in Stark Tower. They've been working side by side and Bruce has his own lab now. He's doing work that augments Tony's own, which could lead to an experiment going wrong...," USA Today quotes.

Comicbook Resources adds, "He does feel more comfortable with himself. His confidence is getting better. But, you know, that gets shaken. His ability to handle the Hulk really gets thrown into question in this film. The hard part is coming back. Hulk doesn't want to cede his place. It's much harder to come back from being Hulk than it is to get into him."

In addition to that, the relationship between Black Widow, played by Scarlett Johansson, and Banner will deepen as the two share something similar together, even calling the two as lost souls.

This doesn't help to the already growing hype as the first trailer for the third Avengers movie ranked 3^rd in the 2014 most viewed trailers where it gave fans a glimpse on how things are going to take a dramatic turn for Earth's Mightiest Heroes. The second trailer for the highly anticipated movie will be revealed on January 12 during the National Championship game.

The original cast will be returning to reprise their roles and will also be bringing along new crew mates in the form of The Vision, who is played by Paul Bettany; Scarlet Witch, who is played by Elizabeth Olsen; and Quicksilver, portrayed by Aaron-Taylor Johnson. The movie will still be directed by Joss Whedon and will premiere on May 2015.
