As the pre-production phase is a vital process in feature-length animation filmmaking, this study focuses on the arrangement of this phase in Iranian animation film projects. They are Mouse and Cat, Tak Taz, Namaki & The Giant, The Sun of Egypt, Jamshid & Khorshid, Simorq’s Heart and Tehran 2121. In support of the investigation of these, the research reviews the background of Iranian cinema, television and animation. It looks also at the emergence and evolution of the pre-production phase in Disney and Pixar studios. Moreover, comparisons of pre-production phases implemented by Japanese, British and Pixar filmmakers are complementary contexts highlighting this process. It comprises four key stages: writing stages e.g. script; visualization stages e.g. concept design; scene setting e.g. storyboard, and a rough version of a film in the form of a story reel (Yun Mou et al, 2013). Implementation of these stages needs strategies to be employed by successful filmmakers. Based on such facts, a theoretical comparison analyses the arrangement of the pre-production phase in the seven projects. The findings indicate two types of factors affecting the arrangement of this phase. Indirect factors such as the dependency on management by government and its financial support constitutes issues influencing productions. Direct factors include filmmakers’ abilities and their direct actions on production.
