'Avengers 2 Age of Ultron' Release Date, Plot News: Hulk to Undergo Changes in Coming Marvel Movie

It goes without saying that the Hulk is an important part of team Avengers. During a recent interview, actor Mark Ruffalo provided additional insight about the character and his role in the upcoming "Avengers: Age Of Ultron" movie which is due to premiere on May 1, 2015.

Ruffalo described how the Hulk will go through some changes as a result of which viewers will see a completely different side of the angry green giant.

Any changes in the Hulk's character could mean a lot of trouble for the other Avengers, but Ruffalo hinted that some of the transformation that Bruce Banner and his green alter ego will go through will be positive. This is mainly because Banner has matured since the events in the first film where the Avengers were supported by S.H.I.E.L.D and, at one point, used by the organization.

However, as S.H.I.E.L.D. is no longer around in "Avengers: Age Of Ultron," the plot will focus more on each character in the Avengers.

Ruffalo described that each of the Avengers will have "their own cool little thing happening."

When questioned if Ultron will be able to control the Hulk, Ruffalo replied obliquely, saying anything could happen in the upcoming film as "Hulk is kind of a wild card. He's the loose cannon of the group. He's more like an atom bomb."

There were also indications in the trailer that Tony Stark tried to find a serum to control the Hulk in case he did not revert to Banner's form, and this inadvertently led to Stark creating Ultron.

A new member in the Avengers named Vision is going to make his debut in "Avengers: Age of Ultron," a character to be played by Paul Bettany. Recently, Vision and his story arc attracted a lot of online chatter with speculation surrounding his costume and whether or not he will sport a red or purple face.
