(ANAHEIM, Calif.) -- Over the weekend, Disney staged its D23 Expo in Anaheim, California, previewing some of its most anticipated films over the next few years.
One of those movies is The Avengers, which will feature Marvel superheroes such as Robert Downey Jr.'s Iron Man, Chris Hemsworth's Thor, Chris Evans' Captain America and many more.
Despite the star power in The Avengers, Jeremy Renner and Scarlett Johansson -- who play Hawkeye and Black Widow, respectively -- said the entire cast rarely spent time together on the set. Even so, Downey Jr. said they all took a professional approach to the film.
"I think the challenge is to buy into what you're doing, and not take yourself too seriously but take the work seriously, and I think everybody had the right attitude. You know, it's not rocket science but it's not easy," Downey Jr. said.
The Avengers will be released next May.
Also at the D23 Expo, Jason Segel promoted his Muppets film, which opens in November. Segel, who wrote the screenplay and is the film's leading star, said he became emotional when the cast read the script for the first time.
He said, "I'm very proud of how much I love The Muppets. All I can say is you would cry too. When Kermit comes out and starts saying stuff you've written, it is the most awe-inspiring, humbling moment you can imagine."
