15 Stunning Facts About 2017’s Biggest Movies

7. A Make-A-Wish Kid Wrote The "Friend From Work" Line - Thor: Ragnarok

One of the funniest lines from Thor: Ragnarok was used extensively in the film's marketing. When Thor arrives on Sakaar and realises that he's about to face off against The Hulk, he hilariously quips, "We know each other! He's a friend from work!"

Though on the face of it this sounds like a line that director Taika Waititi would come up with himself or maybe Chris Hemsworth would improvise, it was in fact suggested by a child who was visiting the set with the Make-A-Wish Foundation.

Hemsworth said of the boy's contribution to the script, "We had a young kid, a Make-A-Wish kid on set that day. In between the takes I was talking with him, kind-of going back and forth. And he goes, 'You know, you should say, he's a friend from work!' So that young man actually came up with it."

Considering how popular the line is with fans, it's quite an achievement for a youngster, especially one suffering through life-threatening illness, and a testament to the fast-and-loose nature of Waititi's directing style that promotes improvisation.
