The Walt Disney Co. plucked from a rival film studio in Burbank for its new chairman of The Walt Disney Studios.

Alan Horn will begin in his new position at Disney on June 11. He had been at Warner Bros. for 12 years, most recently as president and COO of Warner Bros. Entertainment.

Horn replaces Rich Ross who left Disney following the dismal box office performance of “John Carter.” The film flop resulted in Disney reporting an $84 million loss in operating income for the quarter for the studio entertainment division.

Horn was chosen as studio chairman for his appreciation of movie making as an art and a business, said Disney Chairman and CEO Robert Iger.

“He’s earned the respect of the industry for driving tremendous, sustained creative and financial success, and is also known and admired for his impeccable taste and integrity,” Iger said in a prepared statement.

At Warner Bros., Horn had oversight of the studios’ theatrical and home entertainment operations. During his tenure the studio released the eight films in the Harry Potter series, “The Dark Knight,” “Happy Feet”, and “Sherlock Holmes.”

Before joining Warner Bros., Horn co-founded Castle Rock Entertainment where he served as chairman and chief executive officer.

“I’m incredibly excited about joining The Walt Disney Company, one of the most iconic and beloved entertainment companies in the world,” Horn said in a prepared statement. “I love the motion picture business and look forward to making a contribution as part of Bob Iger’s team working closely with the dedicated and talented group at the studio.”
