According to a Vanguard Animation press release:

Ewan McGregor, star of Moulin Rouge and Star Wars, will voice the title character in Vanguard Animation’s CG animated feature film Valient. The animated comedy tells the story of a lowly wood pigeon named Valiant, who overcomes his small size to become a hero in Great Britain’s Royal Air Force Homing Pigeon Service during World War II. The RHPS advanced the Allied cause by flying vital messages about enemy movements across the English Channel, while evading brutal attacks by the enemy’s Falcon brigade.

Sexy Beast star, Academy Award-winner Sir Ben Kingsley, will voice General Keyserlingk, the feared German falcon leader. Other actors lending their voices include Academy Award-winner Jim Broadbent (Moulin Rouge, Bridget Jones’s Diary), Rupert Everett (An Ideal Husband, My Best Friend’s Wedding), Hugh Laurie (Stuart Little), John Hurt (Harry Potter, Elephant Man), and Ricky Gervais, star of the BBC comedy hit series The Office.

Valient, which will be completed in December 2004, is currently in production. Disney is distributing the picture in North America, and Odyssey Entertainment in the UK is handling international distribution.
