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.

Augustus: Between the three of us, we have 5 legs, 4 eyes, 2 1/2 working pairs of lungs, but we also have 2 dozen eggs, so I'd go back inside if I were you.

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.
