The Secret World of Arrietty

Arrietty, titled The Borrower Arrietty (借りぐらしのアリエッティ Kari-gurashi no Arietti) in Japan and The Secret World of Arrietty in North America, is a 2010 Japanese animated fantasy film by Studio Ghibli, based on Mary Norton's juvenile fantasy novel, The Borrowers. The film was directed by Hiromasa Yonebayashi, and written by Hayao Miyazaki and Keiko Niwa.

Dubbing History
Two different English dubs were produced for Arrietty. The first dub was produced by Optimum Releasing for a U.K. release, and released July 29, 2011. Why Optimum chose to produce their own dub is unclear, though it's believed that Optimum wanted to release the film in the UK before Disney's American dub was ready. It may also be due to Arrietty being based on an English novel. This version of the dub is also released in Australia.

Disney's dub would be released to theaters on February 17, 2012, under the title The Secret World of Arrietty. The North American dub was directed by Gary Rydstrom, produced by Frank Marshall and Kathleen Kennedy and written by Karey Kirkpatrick. The names of the humans were westernized in the Disney dub.
