 Adamson also desired to make the film larger in scale ; " I 've gained confidence having gone through the first . This time , I was able to go larger [ in ] scale , with more extras and bigger battle scenes . " Inspired by a passage in the novel where Reepicheep says he would like to attack the castle , a new battle scene in which Peter and Caspian make an attempted raid on Miraz 's castle was created . Adamson felt the imagery of mythological Greek creatures storming a castle was highly original . Markus and McFeely used the sequence to illustrate Peter and Caspian 's conflict and Edmund 's maturity , in an effort to tighten the script by using action as drama . Adamson preferred subtlety to the drama scenes , asking his young male actors not to perform angrily . Adamson copied Alfred Hitchcock by " tell [ ing ] people at the end of the scene , ' Now just give me something where you 're not thinking about anything . ' By using it in context , the audience will read an emotion into it . "
