Don Jon is about a man who’s obsessed with pornography. We doubt any GQ readers could identify with this scenario, but that aside, what attracted you to playing the love interest of a porn hound?
I would say it’s particularly close to home – I’m kidding. It’s more the opportunity to collaborate with Joe [Gordon-Levitt, the director]. The film has some very romantic qualities but they’re funnelled through an unexpected scenario.

Not unlike Lost In Translation. We’ve always associated you with karaoke since that film, and then we read that you went into a bar and sang the Beatles’ “Rocky Raccoon” with a band. Would that be your default karaoke song?
I like “Rocky Raccoon” but I’d normally go for Billy Joel or Fleetwood Mac. “Landslide” is great if you really want to bring the mood down. I still love karaoke. Last winter I was going at least once or twice a week.

The previous campaign you did for Dolce & Gabbana The One fragrance sees you firing back witty answers to a lot of journalists’ questions, many of which seem quite dumb. What’s the stupidest question you’ve been asked by a journalist?
I remember a female interviewer being really interested in what kind of underwear I wore under my outfit in The Avengers. At first I was giving her sort of, “Well, you’ll just have to wait and see” type answers. But eventually I was just like, “You’ve got to be f***ing kidding me.”

You’ve been the face of the fragrance for a while now – so can you explain exactly what a “top note” is?
I think a top note is what hits you first, before deeper notes emerge. I like citrusy fragrances.

You’re going to be 30 next year. Does it hold any fears?
No, I don’t think so. I look forward to ageing gracefully. I wouldn’t want to go backwards.

The Curious Case of Benjamin Button was a cautionary tale in that respect.
Exactly. I don’t want to end up like that guy. I’m looking forward to what the future holds.

Well then, is there anything British men could do to make ourselves more attractive to you?
Do you mean like working out? Because I don’t care about abs and that stuff.

We will pass that happy message on to the British male public.
So that they can let it go? Oh, wait a minute, I don’t want to be responsible for a rise in British male obesity…
