the United States, and dubbed into 25 languages for its worldwide release. More than 12,000 release prints were distributed, which is the largest in Paramount Pictures' history. Although Spielberg insisted his films only be watched traditionally using a film projector at theaters, Paramount chose to release the film in digital cinemas as part of a scheme to convert 10,000 U.S. cinemas to the format. The Kingdom of the Crystal Skull is also notable for being the last film in the series to be distributed by Paramount, as Walt Disney Studios will release the upcoming fifth film, since its parent company's acquisition of Lucasfilm in 2012.
