Of course, that's right now, and things could potentially change, but Downey appeared firm in his denial at the moment. "There isn't one in the pipe," he said. "No, there's no plan for a fourth Iron Man."
Given that the Iron Man films have, Avengers aside, been Marvel's biggest earner, there will certainly be more from Stark, but with the actor's deals growing ever richer in comparison, we may end up with a new Tony before the next lone Iron Man film.
Happily, there will be plenty more Robert Downey Jr. on the horizon. He's part of Avengers: Age Of Ultron, which arrives here on 24 April next year, and he has also signed up for the third Marvel team-up. His latest non-Marvel effort, David Dobkin's (Wedding Crashers) The Judge, had its premiere at the Toronto Film Festival recently and will be out in the UK on 17 October.
