Tom Hiddleston took part in "pillow fights" whilst he was in boarding school.
The 36-year-old actor spent his childhood at school away from his parents, and said the experience led him to meet some of his closest friends, with whom he would often get up to mischief such as fighting with other dormitories.
He said: "Some of the friends I made there are some of my closest friends, because you're all lumped together and you're away from home, so you try and think of crazy things to do.
"I remember we used to - I mean I was eight or nine, right - and you're in dormitories of 10 boys. And it's like 'Okay, what are we gonna do tonight? Okay, we're gonna dorm raid.' Which means you're going to get your pillows after lights out, get the pillow at the end of the pillow case, make it a club, and go and start a huge pillow fight with the next door dormitory. The winner is determined by how many pillows you destroy, basically. You just want there to be feathers everywhere.
"You never forget those moments."
And the 'Kong: Skull Island' star likened his time in boarding school to that of fictional wizard Harry Potter, only without the magic.
He added during an appearance on 'Jimmy Kimmel Live' on Thursday (09.03.17): "I always say boarding school is kind of like a mixture between 'Harry Potter' and 'The Great Escape'. Without the magic, or the second world war. But with plenty of broomsticks."
And Tom isn't the only celebrity to have spoken out about their time at boarding school, as fellow actor Damian Lewis previously spoke out how his time in the strict schooling system shaped him as a person
He said: "There is a latent anger in a lot of people that went to boarding school at an early age. I was eight and I loved it over the five years. But I think the adjustments for eight-year-olds are a lot. And I think it informs who you are for a long, long time.
"But if you learn a mechanism that early to deal with situations that are foreign to you - trying to find your place within a group - you naturally suppress a lot of your own instincts. And I think exercising that amount of control is very clearly related to outbursts of anger later on."
