Emilia Clarke is stunning in scarlet on the cover of the new issue of Harper's Bazaar and inside she dishes on packing heat with Terminator Arnold Schwarzenegger.

The 28-year-old English actress hits the big screens July 1 as Sarah Connor in Terminator Genisys and tells the magazine that it was a blast hanging with the action icon.

'It never gets old. He was so much fun. I expected this massive ego to turn up, but he is this charming, sweet, kind man,' she said. 'He got really excited to film the scenes.'

After five years as the Mother Of Dragons on HBO's blockbuster Game Of Thrones, Clarke relished the chance to change it up a bit as the gun-toting Connor in the sci-fi adventure.

But it required some extra workouts for the petite brunette.

'The hours were so long and the guns were so heavy, so I had to get myself into a place where I wouldn't crap out at four o'clock,' she revealed.

'And also I am the only girl, so I wanted to be like, 'Hey, boys, let me give you a run for your money.'

Starring in the Terminator reboot is likely to take Clarke, who was an unknown when she was cast as Daenerys Targaryen in 2010, to a whole new level of fame.

'Game of Thrones opened a lot of doors,' she says. 'It opened them all.'

But she says those close to her are still not quite used to the recognition that comes with Hollywood success.

When she's out with family or friends, she tells the magazine, 'and someone stops me and says, 'Oh, can I have a picture?,' they keep forgetting that anyone knows me!'

And the actress herself is still a huge fan.

'I was at a Golden Globes after party and Channing f***ing Tatum came up to me, and his stunning missus, Jenna Dewan. And they said, "We call each other Moon Of My Life and My Sun And Stars and all that,"' she recounted.

'And I was like, "I cannot contain this. Please, can we all have something sexual together? You’re both beautiful, even just a hug."''
