Actor John Krasinski has admitted he was regularly mistaken for George Clooney's assistant on the set of their upcoming movie Leatherheads.

Krasinski, who co-stars with Clooney and Renée Zellweger in the romantic comedy, told Us.com: "Walking around with George, you get all the attention, but then you realise people think you're his personal assistant. They say, 'Hey boy, go get us a drink,' and I'm like, 'I'm in the movie too!'"

The 28-year-old also joked about getting in shape for the movie, in which he plays an American football player.

"It's hard being this in shape. Brad Pitt called before Fight Club and wanted tips. I wouldn't give them to him. You can't look this good, that's what I said to Brad!"

Krasinski recently signed up for an untitled comedy from Brit director Sam Mendes. He also stars in NBC's The Office.
