In a Nightline special feature on ABC news, the cast of Captain America: Civil War have a chat, focusing on the "enormous battle" at the airport in Germany.
But when it comes time for Robert Downey, Jr. to talk about his future in the Marvel Cinematic Universe, which currently includes Spider-Man: Homecoming and the two-part Avengers: Infinity War films, RDJ dropped a surprising line.
"I feel like I could do one more," Downey, Jr. said of another solo Iron Man film.
It's the first time that RDJ has said that he'd be willing to do an Iron Man 4, a proper solo movie sequel for the character. Where exactly that would fit in is hard to say, though. There may be room for it if some films currently on the Marvel schedule are shifted around, but whether it would actually come before, in-between, or after Infinity War is hard to say.
Captain America: Civil War hits theaters May 6, 2016, featuring Downey as Iron Man, Chris Evans as Captain America, plus Scarlett Johansson, Elizabeth Olsen, Anthony Mackie, Don Cheadle, Paul Bettany, Sebastian Stan, Jeremy Renner, and Paul Rudd all returning, and the debut of Tom Holland as Spider-Man and Chadwick Boseman as Black Panther.
