The Fault in Our Stars (2014)

Other mistake: In the book Hazel is reading near the start of the film, the word 'to' is used 4 times in a row.

Hazel: Even though you have freaking cancer, you are willing to give money to corporation for a chance to acquire even more cancer? Let me just assure you that not being able to breathe SUCKS. Totally disappointing. Totally.
Augustus: They don't kill you unless you light them. And I've never lit one. It's a metaphor, see: You put the killing thing right between your teeth, but you don't give it the power to do its killing. A metaphor.

Trivia: When Augustus, Hazel, and her mother return from Amsterdam and they show her dad with his sign, there is one to the left of him that says "Godfrey" which refers to one of the producers, Wyck Godfrey.
