A year after their last trip to Narnia, Lucy (Georgie Henley) and Edmund (Skandar Keynes) Pevensie are staying with their obnoxious cousin Eustace Scrubb (Poulter). Dragged back into the magical world via a nautical painting in Eustace's house, the trio find themselves all at sea until they are picked up by Narnian ship The Dawn Treader.
Crewed by old pals Prince Caspian (Ben Barnes) and feisty mouse Reepicheep (Simon Pegg) and captained by the kindly Lord Drinian (Gary Sweet), the Dawn Treader is on a quest to rescue the Seven Lords of Narnia who were banished by Caspian's evil uncle Miraz.
Joining the expedition, Lucy and Edmund soon find themselves on a perilous journey that will take them to the very edge of Narnia and into the company of many wondrous beasties, from the one-footed Dufflepuds to a very moody dragon indeed.
In this bright, breezy and expansive fantasy, The World Is Not Enough director Michael Apted manages to capture the sense of wonder that is so central to CS Lewis's novels.
Liam Neeson returns as the voice of Aslan, but keeneared viewers might notice that Simon Pegg has replaced Eddie Izzard as the voice of intrepid rodent Reepicheep. More noticeable is the casting of talented youngster Poulter, who is fabulously petulant as sulky Scrubb.
