The Warner Bros. Pictures Group brought in $1.8 billion in domestic box office receipts in 2011 from a slate of films led by “Harry Potter and the Deathly Hallows – Part 2.” Internationally, the Burbank-based studio brought in $2.87 billion for a total of $4.7 billion for 2011. Warner Bros. Pictures Group exceeded $4 billion in global revenues for three consecutive years, a record that no other studio has achieved, the company said. “Deathly Hallows – Part 2” was the single most successful film released by Warner Bros. during 2011 with a worldwide box office gross of $1.33 billion. Other films grossing more than $100 million during the year included “The Hangover Part II” and “Horrible Bosses.” “We share these successes with our production partners, as well as all those who worked so hard, not only to make the movies but to bring them to a worldwide audience,” said Warner Bros. Pictures Group President Jeff Robinov in a prepared statement.
