Mr. Wright insists that he did not set out to write an exposé. “Why would I bother to do that?” he said. “Scientology is probably the most stigmatized religion in America already. But I’m fascinated by it and by what drives people to Scientology, especially given its image.”
He added: “There are many countries where you can only believe more or you can believe less. But in the United States we have this incredible smorgasbord, and it really interests me why people are drawn to one faith rather than another, especially to a system of belief that to an outsider seems absurd or dangerous.”
Mr. Wright, whose previous book, “The Looming Tower:” Al-Qaeda and the Road to 9/11,” won the Pulitzer Prize in 2007, is no stranger to writing about secretive organizations. In the case of Scientology, he said, he had been looking for what he calls a “donkey” ”” a character strong and sympathetic enough to carry a complicated story. “I don’t mean it in a disparaging way,” he explained. “A donkey is a very useful beast of burden.” In 2010 he finally found one in Paul Haggis, the winner of back-to-back Oscars for “Million Dollar Baby,” which he wrote, and “Crash,” which he wrote and directed, who defected from Scientology in 2009, after 34 years in the church, during which he rose to one of its highest ranks.
