Perry Moore, an executive producer of the fantasy movie series “The Chronicles of Narnia” and the author of “Hero,” a book about a gay superhero, died on Thursday after being found unconscious in his Greenwich Village apartment. He was 39.

A police spokesman, Detective Joseph Cavitolo, said that investigators were waiting for a medical examiner’s report on the cause, but that there was no suspicion of a crime.

Mr. Moore helped produce the three “Narnia” movies, based on novels by C. S. Lewis, about the adventures of a group of children guided by a talking lion who is in fact the king of Narnia. The series grossed over $1.5 billion and is the 16th-highest-grossing film series in history, according to BoxOfficeMojo.com.

For several weeks in December 2005 and January 2006, an illustrated book written by Mr. Moore about the making of the first movie in the series, “The Chronicles of Narnia: The Lion, the Witch and the Wardrobe,” was on The New York Times’s paperback best-seller list.
