In this article Gabrielle Houle examines the dramaturgical process that actor Marcello Moretti applied to his creation of Arlecchino's body in Giorgio Strehler's globally acclaimed productions of The Servant of Two Masters at the Piccolo Teatro of Milan between 1947 and 1960. She provides a critical analysis of Moretti's interdisciplinary and trans-historical research and creative process, including his study of iconographic representations of the commedia dell’arte, his observation of farmers in Padua in the mid-twentieth century, and the connections he made between his life experiences and his understanding of Arlecchino. She then examines Moretti's acting style, signature postures, and footwork, both as the international press described them and as she observed them in a video recording and in photographs of the productions. The article, based on extensive archival research at the Piccolo Teatro and on interviews with artists who knew both Moretti and Strehler, concludes with a discussion of Moretti's legacy within and beyond Italy.
