Joss Whedon, director of the upcoming "Avengers: Age of Ultron," and Marvel Studios president Kevin Feige sat down with Empire Magazine and discussed the artwork depicting an epic battle between the Hulk and Iron Man, Comic Book reported.

The piece, which was unveiled during the recent Comic Con, showed Tony Stark donning his huge Hulkbuster armor as he goes up against Bruce Banner's green rage monster.

The filmmaker revealed that he really wants to make the battle between the two characters happen. He believes the fight will serve as an important part of the film.

Whedon added that if there are two Avengers members who will go head to head, then Stark and Banner will be the perfect candidates. According to the director, this is due to the two's interesting relationship, according to International Business Times.

"It makes sense because there's no one who can really go up against Hulk, but more importantly, those guys are best friends, so what that battle is and what it means is fascinating to me," the director said.

In the first "Avengers" film, Marvel fans already got a glimpse of the budding friendship between Robert Downey Jr.'s Stark and Mark Ruffalo's Banner. Ruffalo even made a cameo appearance at the end of "Iron Man 3" as the bored and uninterested impromptu therapist of Stark.  

Aside from Banner's appearance, "Iron Man 3" also briefly showcased the Hulkbuster armor as one of the suits that Stark summoned to battle Aldrich Killian's army, Cinema Blend reported.

Although the Hulkbuster along with the other exoskeleton suit models were destroyed in "Iron Man 3," Feige hinted that the anti-Hulk armor will still make a comeback in future films.

The studio head added that Stark originally created a suit for emergency situations, particularly if the Hulk rampages against the Avengers.

"It's a bespoke suit," Feige said. "The back-up plan in case things go awry."

"Avengers: Age of Ultron" will debut on May 1 of this year.
