Robert Downey Jr has joked that he will have "a crisis" when he leaves his Iron Man suit behind.
The 48-year-old actor - who jumps back into the metal armour again for Iron Man 3 - admitted that he has to savour every moment of being the superhero.
"At whatever point I'm done with this, I'm going to have a bit of a crisis, because I probably haven't even fully ingested how much I've enjoyed it, how much it's meant," he told US GQ.
"It so came out of kind of relative obscurity as this second-tier character from the Marvel universe, and I feel I was part of making it something more. But it also to me was just good filmmaking."
Robert, who has also starred in Guy Ritchie's Sherlock Holmes films, Due Date and Zodiac, hinted at a forthcoming retirement from the superhero franchise after suffering an ankle injury during a stunt.
"It got me thinking about how big the message from your cosmic sponsor needs to be before you pick it up. How many genre movies can I do? How many follow-ups to a successful follow-up are actually fun?" he said.
The actor is set to co-star in a film he is producing with his wife Susan Levin, a drama called The Judge, in which he plays Robert Duvall's son.
"It's funny as hell, but speaking of emo, it's just openly weeping reading the script. I don't know how I'm going to get through it. It's me and Robert Duvall, a father and son," he explained.
