When watching a romance between two cancer struck teens unfold, you need some comic relief. And in "The Fault In Our Stars" (out June 6), that comic relief is Nat Wolff.

In the movie —based off of the best selling book by John Green —Wolff plays Isaac, a teen going blind from eye cancer. But what devastates him more than going blind is that his super hot girlfriend dumps him. OK, so a teen with eye cancer who gets dumped isn't exactly cheery, but it's Wolff's irreverenceand funny one-liners that make him a stand out in this movie.


Still, it is depressing and Wolff says he couldn't help but become depressed in real life during filming. "I thought I'd have the least heavy job, but then I realized it was way deeper and upsetting than I thought it would be," he tells us. "[It was challenging] trying to find how Isaac was using humor to deflect his pain, but then I realized that's what the whole movie is about; dealing with pain in realistic ways."

Before he started filming, Wolff was adamant about meeting real teens with cancer to get a better handle on his character. Amazingly, he met a guy who was going through the same exact predicament his character was going through: going blind and getting dumped. "I learned kids with cancer are just like anyone else. They're still getting dumped, they can still be a--holes, or they can be great but they aren't perfect. And they still want to have sex," he says.

Wolff also wore blinding contacts while filming and lived two days completely blind. "I put Tiger's Balm on my toothbrush which almost killed me," he says. "But you realize you have to smell your toothbrush when you're blind."

During filming, Wolff became close with everyone on set, including fellow young actors Shailene Woodley and Ansel Elgort, as well as author John Green. Wolff, who is in a rock band with his younger brother Alex, especially bonded over music with Elgort, who is a DJ. The small cast is especially protective of the love story they're telling, but Wolff hopes it affects movie goers as much as it has affected him. "It's powerful. It shows how powerful love is. And even if you live a still life, you can live a full life."
