Iron Man 3 star Ben Kingsley teased a "secret Marvel project" while making press rounds for his upcoming Ender's Game.
"It's a secret Marvel project," the 69-year-old said. "I'm not allowed to say any more, you're going to have to wait and see."
It is unknown whether Ben Kingsley was talking about a new project, or if he will be appearing in a future Marvel movie. But there are a few possibilities for the Oscar winner's next role. Right now, Marvel has The Fantastic Four reboot and two The Amazing Spider-Man sequels in development, while The Avengers: Age of Ultron and Edgar Wright's Ant-Man are currently in pre-production. Should Kingsley be returning as The Mandarin, he could show up in the Age of Ultron, in which Robert Downey Jr. will reprise his role as Iron Man.
Kevin Feige, president of production at Marvel, confirmed in August that the studio has films planned up until 2021, with three untitled movies planned for 2016 and 2017. Feige hinted that these films will be the beginnings of other franchises and will expand the Marvel universe, which opens up more possibilities for Kingsley's return.
Ben Kingsley also said he was excited to reunite with some Iron Man 3 crew for Ender's Game. He plays Mazer Rackham in the Gavin Hood-directed adaptation of Orson Scott Card's 1985 military science fiction novel.
"I was with many members of the crew that were involved in Iron Man 3. It was lovely to see them again. It was great to be with this wonderful family," he said.
"I think they have enormous taste as creative artists. There's nothing lazy or gratuitous about their work. They are at the top of their game, and they're great company to keep."
In addition to Ben Kingsley, Ender's Game stars Asa Butterfield, Harrison Ford, Hailee Steinfeld, Viola Davis, and Abigail Breslin. The films hits theaters October 25.
