The Fault in Our Stars is a 2014 American coming-of-age romance film directed by Josh Boone from a screenplay by Scott Neustadter and Michael H. Weber, based on the 2012 novel of the same name by John Green. The film stars Shailene Woodley and Ansel Elgort, with Laura Dern, Sam Trammell, Nat Wolff, and Willem Dafoe in supporting roles. The story centers on a sixteen-year-old cancer patient, played by Woodley, forced by her parents to attend a support group, where she meets and subsequently falls in love with another cancer patient, played by Elgort.

Development began in January 2012 when Fox 2000 Pictures optioned the film adaptation rights to adapt the novel into a feature film. Principal photography began on August 26, 2013, in Pittsburgh, with a few additional days in Amsterdam, The Netherlands, before concluding on October 16. Pittsburgh doubled for all of the scenes set in Indianapolis, Indiana, the novel's setting, as well as for some interior scenes set in Amsterdam.
