"Paper Towns" debuts first trailer, with Cara Delevingne and Nat Wolff

If you loved (and likely cried) over the book and movie versions of John Green's "The Fault in Our Stars," then you'll want to sit down and hit play on the new trailer for "Paper Towns," adapted from his bestselling book of the same name.

The first look at the film, starring Nat Wolff and Cara Delevingne, arrived online Thursday. The story centers around Q (Wolff), who falls for the girl next door, Margo (Delevingne). They grew up together, but by their senior year of high school they barely speak -- until one night when Margo appears at his bedroom window and enlists him in a campaign to get revenge on those who've hurt her. The next day, she disappears and he must to decipher clues to try and find her.

"Paper Towns" marks Delevingne's first major film role (though she's had small parts in "Anna Karenina," "The Face of an Angel" and the upcoming "Pan"). Green told USA Today he was initially hesitant to cast the 22-year-old British model. "When I heard she was auditioning, it was like, 'No.' Of course I thought that was crazy," he revealed. "But then I saw the audition. She understood Margo in ways that no one I have ever met understands Margo."

Wolff, meanwhile, appeared alongside Shailene Woodley and Ansel Elgort last year in "The Fault in Our Stars" as Augustus' best friend, Isaac.

Directed by Jake Schreier, "Paper Towns" will arrive in theaters July 24.
