10 things to know about ‘The Fault in Our Stars’ (and why you need to see it)

On its surface, The Fault in Our Stars doesn't look like your typical summer blockbuster.

An adaptation of the young adult novel of the same name, the film follows a 16-year-old cancer patient named Hazel (Shailene Woodley) as she falls in love with a 17-year-old ex-basketball player named Augustus (Ansel Elgorst), who previously lost a leg to cancer.

Earning rave reviews from film critics and fans, the film promises to deliver on love, laughs and yes, plenty of tears, and is already poised to climb the box-office charts.

Here’s 10 things to know about The Fault in Our Stars:

1. The title is a variation of a quote from William Shakespeare's Julius Caesar. The nobleman Cassius says to Brutus: "The fault, dear Brutus, is not in our stars, but in ourselves, the underlings."

2. It’s the second film where real-life friends Shailene and Ansel star together. In Divergent they played brother and sister, while in The Fault in Our Stars they play love interests.

3. Shailene Woodley insisted that Ansel read the novel before his first meeting with filmmakers. "I thought, 'If I tell her I haven't read it, she'll be mad during our audition and it would be a mess,'" Ansel said in an interview. "So I literally read it for Shailene."

4. The film had a paltry budget of just $12 million. (To compare, Tom Cruise’s science-fiction thriller Edge Tomorrow was a budget-buster at $175 million).

5. The film’s trailer has more than 20 million views on YouTube.

6. Author John Green has stated that the inspiration for the book came from his days working as a student chaplain at a children’s hospital. In 2009, he met a teen with thyroid cancer named Esther Earl at a Harry Potter conference and they became friends. Esther lost her battle in 2010. "Icould never have written TFIOS without knowing and loving Esther,” John said.

7. Shailene Woodley was determined to get the role of Hazel. She wrote a long, touching letter to the author about her enthusiasm for the book, and eventually beat out 200 other girls for the part.

8. Real cancer survivors were cast in the support group scene, many of whom had been part of an actual teenage support group while they were ill. Their roles did not require any previous acting experience.

9. The book spent 78 weeks on the New York Times best-seller list.

10. Shailene chopped off her long hair for the role and donated it to Children With Hair Loss.
