Matt Damon was a nightmare child and regularly tormented his parents by throwing temper tantrums.
The Bourne Identity star admits he struggled to keep his anger under control as a young teenager, driving his parents mad in the process.
He says, "I had a brutal temper as a kid.
"When I was 12, I would throw things around the room. I was like a Tasmanian Devil, freaking out at the drop of a hat.
"Luckily I grew out of it."
