Valiant

Set in 1944, Valiant (Ewan McGregor) is a woodland pigeon who wants to become a great hero someday. When he hears they are hiring recruits for the Royal Homing Pigeon Service, he immediately sets out for London. On the way, he meets a smelly, but friendly pigeon named Bugsy (Ricky Gervais), who joins him, mainly to get away from clients he cheated in a game of find-the pebble, and helps him sign up for the war.
