'Avenger 2: Age of Ultron' Plot Details: Iron Man and Hulk to Develop Tension, Stellan Skarsgard to Join

In a recent revelation regarding the plot of "Avengers 2" it has come to fore that The Hulk and Iron Man are going to be at loggerheads in regards to the Ultron project. Iron Man aka Tony Stark would be unhappy about the fact that Hulk aka Bruce Banner is doubtful about former's project, according to the reports by Enstarz.

"Stark has set Banner up in order to be able to continue his good works in Stark Tower," said Downey Jr. to Entertainment Weekly at the 2014 San Diego Comic-Con. "Tony has a project of his own. So it's one of those things where it's like a development team - 'Hey how's it going over there? That looks nice and green. Can I talk to you about this other idea I have?' But it winds up not being such a good idea."

Hulk's non-belief in Stark's project would give rise to the tension between the two.

"Bruce is dubious as to the moral psychology of this project idea of Tony's," said Downey Jr, further, adding "It's nice because it sets up a little bit of tension between us."

Meanwhile, in other piece of news in regards to the cast of the movie, it has been revealed that Stellan Skarsgard would be joining the otherwise huge ensemble cast of the film. In his latest chitchat with Total film print magazine, Stellan said that he shares a long association with Marvel Cinemnatic Universe and he would be seen Joss Whedon's sequel of the blockbuster film, according to reports by Cinema Blend.

Stellan is known for playing Dr Erik Selvig in Kenneth Branagh's "Thor." Though it is unknown what story Stellan's character would have, the Swedish actor did suggest that the audience would get to see great amount of his skin, according to the magazine reports.
