John Green, Cara Delevingne, and Nat Wolff hit the road in exclusive Paper Towns extra

What does Cara Delevingne need for a good road trip? Her answer surprised author John Green — but if you’ve seen Paper Towns, it’s pretty fitting.

The stars of the book-to-film hit the road for an exclusive extra from its upcoming DVD/Blu-Ray release, with Green chatting up the cast as he sits in the driver’s seat.

Road trips, of course, play a major role in Paper Towns. Margo Roth Spiegelman (Delevingne) enlists Quentin “Q” Jacobsen (Wolff) for a late-night driving tour of Orlando to extract revenge on those who wronged her; and then, after Margo mysteriously vanishes, Q and his friends take the Jacobsen family van and set off on a mission to find her.

Watch the clip above for Delevingne’s road trip must-have, a rating of Wolff’s driving skills, and to see what the cast named as their favorite road trip movie (Spoiler alert: they pick the one they’re all in).

Paper Towns comes out on Digital HD this Friday, and on DVD/Blu-Ray Oct. 20. See below for another clip of Green telling EW what he thinks of his Paper Towns stars.
