By now, it'll be hard to ever imagine anyone besides Ansel Elgort and Shailene Woodley as Gus and Hazel in the adaptation of The Fault in Our Stars . But before they were cast, many other actors auditioned for the roles of the soulful teens. Can you imagine Hailee Steinfeld as Hazel or any of these actors in the roles? See what might have been with these seven other actors who were almost cast in The Fault in Our Stars.
Before Shailene Woodley was cast, Steinfeld was also in the running  for Hazel.
This Summer's breakout star Brenton Thwaites (he has a role in Maleficent and as the lead in The Giver) tested for the role of Gus .
Though he was eventually cast as Isaac, Nat Wolff also tested for Gus after he had starred in director Josh Boone's previous film Stuck in Love.
Another Stuck in Love alum, Liana Liberato was rumored for the role of Hazel.
Nick Robinson, best known for The Kings of Summer and Melissa & Joey, was on the short list to play Gus .
The Borgias star Noah Silver also tested for Gus .
Mary Kate Wiles
