Chris Hemsworth heads up an all-star cast for a frantic adventure as he tries to escape the clutches of Jeff Goldblum's evil Grandmaster in Thor: Ragnarok.
When Thor is pitted up against the Hulk in a battle for the Grandmaster's amusement he recognises his old friend and smiles, shouting: "Yes! I know him! He's a friend from work!."
The line made it into the teaser trailer released earlier in the year that broke Marvel/Disney's record for most views in 24 hours - more than 136 million. It has since gone on to become one of the most memorable lines in the whole movie.

Hemsworth admitted in an interview with Entertainment Weekly that the line was not scripted, and was actually created by a kid visiting the set from the Make-a-Wish Foundation.
He told EW: "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."
Taika Waititi famously keeps his sets pretty informal, and some reports have said that up to 80 per cent of the dialogue in the film is improvised.

The director - who has several critically acclaimed comedies under his belt, such as What We Do In The Shadows - also encouraged his cast (a sick line-up including Cate Blanchett, Tom Hiddleston, Idris Elba, and Anthony Hopkins) to dance, play music, and crucially, improvise lines.
The laid-back approach left some of the actors who are used to more tightly controlled, scripted shoots feeling guilty about the level of freedom they got on set.
According to Waititi, Mark Ruffalo, who plays Thor's Avengers companion The Hulk, was one such actor. He said: "Mark Ruffalo would be finished shooting for the day, and he'd come up to me and he'd be like, 'Why have we not been fired yet? We are doing the most insane stuff in this film, so where's the phone call?'"
Thor: Ragnarok is still in cinemas and has grossed more than $752 million (£563m) so far.
