The third of the movie Chronicles of Narnia sees the youngest Pevensies Lucy and Edmund reuniting with Prince Caspian aboard the good ship Dawn Treader. Their mission is to find the Seven Swords of the missing Seven Lords and defeat the evil emanating in the form of a sinister green mist from Dark Island. More sophisticated and slicker than Prince Caspian, this neatly combines darker themes and top-notch action, particularly a terrifying sea serpent, to keep the ongoing series firmly on the boil.
Just when the Chronicles of Narnia were making heavy weather of things with the distinctly choppy Prince Caspian, this third instalment sees them firmly back on course.
Prince Caspian (Barnes) has been joined by the younger Pevensies Lucy (Henley) and Edmund (Keynes) aboard the Narnian sailing ship The Dawn Treader as it embarks on a Homeric quest for seven swords.
Joining the crew are the slightly irritating mouse Reepicheep (Pegg) and the Pevensies' extremely irritating cousin Eustace (Son of Rambow's Poulter), a spoilt brat with just a hint of stage-school kid about him.
The swords - which belonged to the missing Seven Lords banished by Caspian's evil uncle Miraz - must be laid on Aslan's table if the evil drifting out of the foreboding Dark Island in the form of mist is to be banished.
The trouble is Dark Island is a fair trek away...and before they get there our heroes must confront brutal slavers plus a river that turns things (and people) gold.
Intriguingly, they must also overcome their mortal weaknesses, which are tested by the disturbingly canny mist in a series of scenes where Lucy's vanity threatens to overcome her and the White Queen again puts temptation in Edmund's way.
Veteran director Michael Apted opts for the virtues of old-fashioned storytelling to craft a cracking adventure yarn shot through with some - but not too many - psychological overtones.
Owing a sizeable debt to Lord of the Rings, it nevertheless manages to forge its own character, boasting a handful of genuinely impressive setpieces, none more so than the scene where Eustace is transformed into a fire-breathing dragon.
