Idris Elba let it slip in an interview that he'll appear in "Avengers: Age of Ultron" as his "Thor" character, Heimdall. Here are some of our other favorite faces from Marvel's world:
At Marvel's presentation Tuesday, the studio announced that "42" star Chadwick Boseman will play the comic-book hero Black Panther, who will be key to the plot of the forthcoming "Captain America: Civil War." He's the latest in a line of fascinating superheroes.
Rumor has it that Benedict Cumberbatch is in negotiations to play Marvel's Doctor Strange, but Marvel kept mum at its announcement. Still, the film is due out in 2016.
The first "Avengers" movie, released in 2012, is the third highest-grossing movie of all time -- and a new one, "Age of Ultron," is due out next summer. The trailer already has people buzzing. Two more will come out in 2018 and 2019.
Robert Downey Jr. brought Tony Stark's Iron Man to life in 2008. There have been two sequels, and Iron Man was a major star in "The Avengers."
Mark Ruffalo got to wear the Hulk's stretchy purple pants in "The Avengers," and he will be in the sequel as well. Eric Bana and Edward Norton played the character in two previous movies: "Hulk" (2003) and "The Incredible Hulk" (2008).
Following in Tobey Maguire's footsteps -- err, spider webs -- Andrew Garfield starred in 2012's "The Amazing Spider-Man." He also played the part in a sequel this year.
Halle Berry's Storm and Hugh Jackman's Wolverine became fan favorites when "X-Men" hit theaters in 2000. The pair have also appeared in the series' many sequels, including "X-Men: Days of Future Past" this year. (Wolverine has even had two movies of his own.)
The late Christopher Reeve, pictured, wore the red cape in 1978's "Superman" and its three sequels. Brandon Routh took over in 2006's "Superman Returns," and Henry Cavill starred in 2013's "Man of Steel."
Chris Evans, who first donned red, white and blue for 2011's "Captain America: The First Avenger," continued his fight against evil in "The Avengers." He reprised his role this year in "Captain America: The Winter Soldier," and he'll be in the second Avengers.
Following Michael Keaton in 1989 (and 1992), Val Kilmer in 1995 and George Clooney in 1997, Christian Bale drove the Batmobile for all three of the Batman movies directed by Christopher Nolan.
Chris Hemsworth played Thor in the 2011 film of the same name. There was also a sequel in 2013, and Thor, of course, is one of the Avengers.
Ron Perlman went red for Guillermo del Toro's "Hellboy" in 2004 and "Hellboy II: The Golden Army" in 2008.
"Captain America" wasn't Chris Evans' first time battling evil in a form-fitting blue suit. Evans, Ioan Gruffudd, Jessica Alba and Michael Chiklis were the "Fantastic Four" in 2005. They teamed up again in a 2007 sequel.
Ryan Reynolds became the Green Lantern in 2011.
Mikey Kelley, James Arnold Taylor, Nolan North and Mitchell Whitfield voiced the Teenage Mutant Ninja Turtles in 2007's "TMNT." Everyone's favorite pizza-eating reptiles returned this year in a live-action reboot.
- Idris Elba's confirmed he'll be in "Avengers: Age of Ultron"
- The actor added that Tom Hiddleston will appear in the movie, too
- "Avengers: Age of Ultron" opens in May
(CNN) -- The cast of Marvel's "Avengers: Age of Ultron" just keeps getting better.
On Sunday, "Thor" co-star Idris Elba let it slip in an interview with the UK's Telegraph that he and Tom Hiddleston will appear in next May's "Avengers" sequel.
Elba, 42, has played the Asgard guardian Heimdall in both "Thor" and "Thor: The Dark World," while Hiddleston has portrayed Thor's half-brother, Loki.
Elba didn't specify much about his role in "Age of Ultron," but he did mention that the two men will have a scene with Chris Hemsworth's hammer-wielding Thor.
"I'm in Avengers," Elba confirmed while talking about balancing his career as a DJ with his work as an actor. "I'm doing a scene with Chris Hemsworth and Tom Hiddleston, and they're like, 'Aren't you (meant to be) in Ibiza?' "
Elba's the first to admit that being a Marvel star isn't easy, something he realized when he was transitioning between his work on the Nelson Mandela biopic "Mandela: Long Walk to Freedom" and on "Thor: The Dark World."
"I'd just done eight months in South Africa. I came to England, and the day I came back, I had to do reshoots on 'Thor 2,' " Elba said. "I was like, 'This is torture, man. I don't want to do this.' My agent said: 'You have to; it's part of the deal.' "
Of course, Elba stuck it out, and now he's the latest star to watch for in "Avengers: Age of Ultron," which is scheduled to open on May 1.
