Nothing prepared Wyck Godfrey for the success of “The Fault in Our Stars.”

With hits like “Dear John,” “I, Robot” and the “Twilight” franchise to his credit, the producer is no stranger to having something to celebrate as box office results roll in over a weekend. But the way audiences have embraced the romantic drama left him feeling “overwhelmed, overjoyed and deeply fulfilled,” Godfrey told Variety.

He said he’s been flooded with emails and calls from fans of the film who have responded  deeply to the story of two teenagers who fall in love after meeting in a support group for cancer patients. “Fault in Our Stars” was produced for a mere $12 million, but managed to hold off bigger stars such as Tom Cruise (“Edge of Tomorrow”) and Angelina Jolie (“Maleficent”) to take the top spot at the domestic box office with a $48.2 million debut.

“It’s been the most rewarding weekend of my career,” Godfrey said. “Years ago, when ‘Twilight’ opened I said I’d never be able to duplicate the feeling of that Saturday after it premiered, but this is even more rewarding.”

“It’s such an outlier, because even ‘Twilight’ had vampires,” he added. “It’s just a simple story of two people who fall in love, with characters that make people leave the theater thinking about their own lives and how they want to live them.”

The big screen adaptation of John Green’s best-selling novel represents a major step in the evolution of star Shailene Woodley’s career following the success of last spring’s “Divergent.”

“She’s going to get offered everything in the world, and it will be up to her to choose things she deeply connects with,” Godfrey said.

For Godfrey, the success of “The Fault in Our Stars” comes as his company Temple Hill Entertainment looks to continue to capitalize on a young adult market hungry for big screen romance. He’s already working on adaptations of Ava Dellaira’s debut novel “Love Letters to the Dead” and Nicholas Sparks’ “The Longest Ride,” among other literary properties.

“We’re going to continue to look for material that moves us emotionally,” Godfrey said. “We’re snatching up a lot of books.”
