"Avengers 2: Age of Ultron" is already in its post-production stage and new details regarding the plot of the film are surfacing now and then. The much recent reports suggest that there would be Hulk and Iron Man's fight in the film and it would be emotionally charged. Robert Downey Jr. himself confirmed the fight between the two superheroes.

"It can't just be a good fight, it's gotta be about something," said Downey at the 2014 San Diego Comic-Con, according to HitFix. "And the great thing in 'Age of Ultron' is, that fight between [the Hulk and Tony Stark] is, nobody wins when two people who are friends fight."

The fight scene was filmed in Johannesberg and since then images of Iron Man Hulkbuster's armour have been doing rounds on the internet. Though it is still not clear why the fight between the two would take place, it would be a spectacular scene to watch out for.

Meanwhile, for those who are not aware the "Avenger 2: Age of Ultron" is not going to be based on the "Age of Ultron" book but is an original version by Josh.

"We're doing our own version of the origin story of Ultron....We were crafting our own version of it where [Ultron's] own origin comes more directly from the Avengers we already know about. The other thing is in the origin story there was Hank Pim, so a lot of people assumed he was going to be in the mix, but he's not," said Josh to MTV about the film.

The movie has the basic elements from the comic but there is lot of stuff which is not used as per the Enstarz report.

"Avengers 2: Age of Ultron" is slated to release in theatres in June 2015. The film would have music composed by Brian Tyler.
