During his long and various career as an architect, urban planner, consultant, and editor of the Architectural Review, Gordon Cullen (1914 - 1994) developed innovative and original urban visions.

Despite that, not many studies have been conducted on him, his projects, numerous sketches, or his personal vision about Townscape. This paper addresses this lacuna, offering, in particular, a thorough analysis of a never-published series of sketches part of the Gordon Cullen Archive held at the University of Westminster.

Focusing on this suggesting sequence of images, this paper will investigate in particular Cullen's original approach, describing properly the serial vision as unique cinematic method that he implemented to express and successfully represent the complexity of urban spaces. The main aim is to re-evaluate Cullen's contribution in relation to the seminal urban research of the 50s, 60s, and 70s, stating his crucial role in influencing the contemporary development of urban theories.
