Walter Rastelli began to attend courses in Cinema and Film Direction already during his high school period; to this are added several personal studies in the fields of photography, video editing and 3D animation. After finishing his studies, he moved to Rome where he continued his studies privately at the Libera Università del Cinema in Rome. In the meantime, he attended several sets in the capital, made several amateur short films and joined some friends in the area of Naples, united by a passion for cinema. This led, in October 2016, to the founding of Drazil Production, a cultural association dedicated to the production of low budget short films. In 2017 he enrolled at the Academy of Fine Arts in Naples to obtain a degree in Cinema, Photography and Television. In 2018, to deepen his skills and knowledge of 3D animation, he enrolled in an annual course of Autodesk Maya at the Ilas. Since 2018 he has been co-founder and organizer of the Phlegraean Film Festival, an international short film festival established in the city of Bacoli and in the entire territory of Campi Flegrei.
