 A narcissistic and athletic , yet good @-@ hearted , prince who ends up confused with the world of New York once entering it . Marsden was announced to have been cast on December 6 , 2005 . At the time Marsden was auditioning , the role of Robert had not been cast but he decided to pursue the role of Prince Edward because he was " more fun and he responded more to that character . " Edward is a prince in Andalasia and the stepson of Narissa . He is " very pure , very simple @-@ minded and naive , but innocently narcissistic . "
