 Liam Neeson reprises his role as the voice of the lion Aslan . Aslan is " more parental here , [ he ] lets the kids , well , make their own mistakes " . Aslan 's entrance was filmed as a dream sequence to emphasize his messianic nature , and not make it reflect badly on his absence when Narnia is in turmoil . Although the character is considered C.S. Lewis ' version of Jesus , Neeson " see [ s ] him more as the spirit of the planet – this living , breathing planet . That 's what he stands for , for me ; more what the native Americans would believe . " As Aslan has fewer action scenes than in the first film , the animators found it difficult to make him move interestingly . His pose had to be regal , but if he moved his head too much , he would remind viewers of a dog . As well as having his size increased by fifteen percent , Aslan 's eyes were also changed to look less " Egyptian " . Many of his shots were finished at the last minute .
