Josh Gad he said Jake Gyllenhaal they had no interest in participating The Book of Mormon.

According to his memorial“In Gad We Trust: A Uza-Ena,” released on Tuesday, January 14, Gad, 43, said that Love & Other Medicine The costar warned him not to participate in the production of comedy.

Gadi wrote: “When I was just playing sports The Daily ShowI was also filming a movie called Love & Other Medicine … One day when Jake and I were driving from Pittsburgh, I asked him if I could play a new song that I had done at a conference in New York, hoping to get his advice on whether or not. I have to follow it. He said, ‘Yes, open it,’ and I played the opening number.

Love & Other Medicineand Gyllenhaal, 44, is Anne Hathaway in the lead roles, began filming in Pittsburgh in September 2009. Gad contributed to the story, which follows drug dealer Jamie as he begins a relationship with Maggie, a woman suffering from early Parkinson’s disease.

Gad said in his book that Gyllenhaal, “laughed his ass off,” listening to “Hello!,” the stage’s famous opening number, before Gyllenhaal’s attitude changed.

“I skipped to another song on the album and his face slowly went from happy to scared and scared,” Gad said. “He stopped the car and said, ‘Dude, you can’t do anything.’ This will be very controversial. Who wrote this?’ I stopped the music and looked at him. ‘The South Park guys.’”

Despite Gyllenhaal’s complaints, Gad spent 15 months portraying Elder Cunningham in The Book of Mormon on Broadway, produced by South Park‘s Trey Parker and Matt Stone. Gad’s performance earned him a Tony Award nomination for Best Actor in a Musical in 2011.

Gad said Us Weekly after the release of his memoir that managing the obstacles of his career “became the title of the book.”

“When faced with challenges, how do you overcome obstacles to achieve dreams bigger than you can prepare for?” This is the story of my life,” said Gad Us.

The actor also wrote about having an absent father for most of his life, explaining how it affected his fatherhood. (Gad shares two daughters, Ava, 13, and Isabella, 10, with wife Ida Darvish.)

“I had a hell of a time writing (the book), and I hope everyone who reads it takes away something useful and encouraging,” he said. “At least, I hope he has a good laugh.”
