A U.K. tabloid newspaper has unearthed pictures of North Korean leader Kim Jong-un as a teenager in a musical production at his Swiss boarding school.

The Sun on Tuesday published pictures of Kim in the school production of the iconic Broadway musical "Grease" in 1995.

The tubby North Korean leader appears in the pictures a skinny young boy in a leather jacket and well-oiled hair.

Kim entered the International School of Berne at the age of 11 in 1994 and stayed there until 1997.

He reportedly enjoyed reading comic books and watching American films such as "Jurassic Park." The Sun quoted a classmate as saying he enjoyed singing "Summer Nights" from the musical, which was also a film starring John Travolta.

Ex-classmate Tal Rapp from Israel told the paper, "Everyone now looks at him as a lunatic who hates the world, but the kid I remember was the quietest person I have ever met."
