A nationwide casting effort began in 2007. More than 1,500 teens and young adults auditioned for the four roles. James Maslow and Logan Henderson were the easiest and first actors cast. Kendall Schmidt was the last actor cast, and the most difficult role to cast. The role of Kendall Knight was originally to go to Curt Hansen, who now plays Dak Zevon on the show, but when he appeared a lot older than the others and sounded too much like James in the pick up pilot, the producers auditioned and cast Schmidt after a recommendation by Logan Henderson, who was also friends with the actor before casting. Filming of the series began in August 2009. Actor Carlos Pena Jr. previously worked with Scott Fellows on Ned's Declassified School Survival Guide. As he had just entered the Boston Conservatory to study musical theatre, Pena was reluctant to audition but sent in a tape at the encouragement of his manager. Executive Producer Scott Fellows was inspired to write each character by the personality of the actor playing him.
