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: In Hazel's room there is a poster for the band "Hectic Glow," which is a fictional band that Gus introduces Hazel to in the original book.
