Film Music Reporter has been able to confirm that John Williams is officially attached to score Steven Spielberg’s War Horse. The movie follows a young man named Albert and his horse, Joey, and how their bond is broken when Joey is sold to the cavalry and sent to the trenches of World War One. The movie currently in post-production stars Benedict Cumberbatch, Emily Watson and David Thewlis. While Williams’ involvement in the movie was expected, the composer’s noticeably absence from film scoring in the past couple of years raised concerns in some circles if Williams would indeed be back to score Spielberg’s latest movie. The Dreamworks and Amblin Productions movie is scheduled to be released on December 28, 2011.

As reported on other websites, Williams already has recorded music for the other Steven Spielberg-directed movie opening next year The Adventures of Tintin: The Secret of the Unicorn starring Simon Pegg, Daniel Craig, Cary Elwes and Andy Serkis. In the movie, Tintin and his friends discover directions to a sunken ship commanded by Capt. Haddock’s ancestor and go off on a treasure hunt. The movie is expected to open domestically during Christmas season of next year competing against War Horse, while a European release is planned for November.
