Mr Kim reportedly said he wanted to move to Switzerland, where he spent his childhood at an International School, in search of a time when he had “nothing to be afraid of.”

“He [Kim Jong-nam] text me a message saying I’ll see you in Geneva, I’ll be back in 3 days,” Mischa Aznavour, a school friend of Mr Kim, said in the film.

“He was, like, coming back to Geneva to, err, search back all his youth, like, part of a time where we had nothing to think about, nothing to be afraid of.”
