"Our childhood rivalry was a bit vicious – a bit like The Hunger Games, actually," Liam said. "We had a few incidents with weapons – I never had any problems with Luke because he was so much older and I didn't mess with him.

"But with Chris, we were very likeminded, very stubborn and would often get into arguments and because I was so much younger and smaller I had to use weapons to fight. So one day when I was about 5 we had a fight in the kitchen about using the toaster, or something, and I picked up a kitchen knife and threw it at his head and the handle hit him in the forehead.

"I could have hit him with the other end if I'd wanted to – it was just a warning shot!" he added. But nowadays there’s no sibling rivalry between the Hemsworth boys and Liam says he can always go to his brothers for advice.

"I did a TV show about 10 years ago with Luke and he came in for a day's work,” Liam said. "All the cameras were on me and Luke was trying to distract me all the time – brotherly love!”
