Set during the Second World War, the film follows young Valiant, a brave pigeon from a small village in England who wants to join the Royal Homing Pigeon Service. He sets off to London to sign up, where he meets a scruffy pigeon called Bugsy (Gervais) and the two get shipped off to RHPS boot camp.
Before they even get a chance to properly finish their training, though, they are called in to the fray and dropped over France, charged with the task of carrying home the most important message of the war.
It's always hard to watch an animated film and not compare it to the consistently brilliant output of Pixar, but this one doesn't measure up too badly. The main characters are nicely animated, although less care and attention has gone in to some of the background graphics. More important than the looks, though, is the script, and Valiant doesn't do too badly there either.
As far as childrens' films go, the storyline isn't too clichéd or predictable, the climax is exciting and there are a number of amusing moments in the film, largely thanks to Ricky Gervais playing a similar character to the ones he uses in his stand-up routines. This film is not brilliant, but it is fun for the children and more than bearable for the adults.
