‘Captain America: Civil War’ Cast Could Add Hulk; Mark Ruffalo Teases Big News

The already packed team of superheros in “Captain America: Civil War” just got a whole lot bigger, greener and meaner. Mark Ruffalo has hinted that he’ll reprise his role as Bruce Banner/the Hulk in the 2016 film.

Ruffalo posted the news to his Tumblr page with the accompanying caption: “Welcome to the wild party! Looking forward to this amazing cast.”

The news, if true, would confirm that Thor (Chris Hemsworth) will be the only member of the original “Avengers” team not included in the third “Captain America” film. Ruffalo joins a cast that includes: Captain America (Chris Evans), Iron Man (Robert Downey Jr.), Scarlet Witch (Elizabeth Olsen), Black Widow (Scarlett Johansson), Falcon (Anthony Mackie), Black Panther (Chadwick Boseman), Agent Sharon Carter (Emily VanCamp), the Winter Soldier (Sebastian Stan), Baron Zemo (Daniel Brühl), Hawkeye (Jeremy Renner), War Machine (Don Cheadle) and Vision (Paul Bettany).

“Civil War” is based on one of Marvel comics’ most controversial storylines, pitting Captain America against Iron Man over the issue of superhuman registration. Many of the Marvel Cinematic Universe’s secondary heroes, like those teased at the end of “Avengers: Age of Ultron,” will take sides with the respective heroes in an all-out battle for supremacy. It was revealed earlier this month that the film would bring back an antagonist from the 2008 film “The Incredible Hulk,” which starred Edward Norton as the green monster with a temper problem. General Thaddeus “Thunderbolt” Ross (William Hurt) is one of the latest additions to the cast. Many believed that Marvel Studios was hoping to sweep this not-so-well-received movie under the rug, but now it seems that the Hulk might have a bigger through line in the MCU’s Phase 3 plans leading to “Infinity War” than fans thought.

When last we saw the Hulk [SPOILER ALERT] he had stolen a plane and forced himself into seclusion at an unknown location. While his actions in the first “Avengers” earned him a bit of a pardon from the U.S. government, his rampage through the streets of a South African city made him public enemy No. 1. It’s unclear how he would be brought back into the loop for “Captain America: Civil War” or if he’ll Hulk out again while battling former allies.

The film is scheduled for release on May 6, 2016.

Correction: An earlier version of this article stated that the news was confirmed. Until Marvel announces anything, Ruffalo's comments are up for debate.
