小罗伯特唐尼确认参演美队3，内战确认

Robert Downey Jr. is on the verge of signing on to “Captain America 3,” with Tony Stark’s Iron Man set to play a key role in bringing the Civil War storyline from Marvel’s comicbooks to the bigscreen and trigger the start of a new phase of movies from Marvel Studios.

The actor is in final negotiations to play the billionaire in the yet-to-be-titled third installment, that is slated to begin production in the Spring for a May 6, 2016, release, according to sources close to the discussions. Downey suits up as the superhero in next summer’s “The Avengers: Age of Ultron” as part of a previous deal that also calls for him to reprise the role in “The Avengers 3.”

The new pact is significant for the Marvel cinematic universe considering the plot will pit Stark against Captain America’s alter-ego Steve Rogers, played by Chris Evans, as they feud over the Superhero Registration Act, which forces anyone with superhuman abilities to reveal their identities to the U.S. government and agree to act as a police force for the authorities.

Stark supports the program, but Rogers does not, saying it threatens civil liberties, causing sides to be taken and Rogers, among others, to go on the run to avoid arrest. The moral question and battle with his Avengers teammate essentially makes Stark a villain of sorts in “Captain America 3,” providing Downey with a meaty role he could play out into future Marvel films, including a fourth “Avengers.”

Marvel on Monday announced plans to reboot the Civil War comicbook miniseries in 2015, which will help introduce the story to new readers leading up to “Captain America 3.” The first crossover of Marvel’s biggest characters, including Spider-Man, was published in 2006.
