The Iron Man franchise has been one of Marvel’s biggest smash hits, launching an entire cinematic universe and earning the studio billions of dollars at the box office. But after three standalone movies, the man who plays Tony Stark himself says fans shouldn’t be holding their breath for a fourth.

According to USA Today, Robert Downey Jr. said that the upcoming Captain America: Civil War is basically an Iron Man sequel by itself, even though he doesn’t get top billing.

“In a way it’s Cap 3 but for me it’s like my little Iron Man 4 and then it’s back to the thing we all recognize. Everything pulls over to the side of the road when the thunder of an Avengers thing comes through because that’s how it is until it changes. If it changes.”

That makes sense, since Civil War is really about the feud between Captain America and Iron Man, over the amount of control that the government should have over superheroes. Even though his name isn’t in the title, Tony Stark/Iron Man is equally as important to this story as Steve Rogers/Captain America.

That’s not to say that there won’t be more Iron Man in the future. The next Avengers film will be the two-part Infinity War, which are likely to feature Iron Man in some way. Unless (SPOILER ALERT) Marvel uses Civil War as a way to kill off Iron Man the same way that the comic version of the story was used to kill of Captain America.

Regardless, RDJ as Tony Stark has made staggering amounts of money already. Even if he does get killed off, we know that no one really stays dead in a comic book. Not even in a comic book movie.
