This chapter explores the dynamics of production design in high-budget SVoD (Subscription Video on Demand) productions, with a focus on US-based high-fantasy series filmed in East Central Europe, particularly in Prague. Through a thematic analysis of interviews with local production designers, art directors and other industry professionals, the study investigates how global streaming platforms such as Amazon have reshaped the creative and organisational processes of production design in peripheral media capitals. The research highlights the challenges posed by data-driven decision-making processes employed by streaming platforms, as experienced by local below-the-line workers. A contradiction emerges between the increased demands for building ever more complex, cinematic fantasy universes and the constraints of tight schedules, rapid turnover of creative personnel and unpredictable script changes. Despite the rise of digital VFX and Virtual Production, art departments demonstrate a surprising resilience in their internal operations. They are described as a burdened workplace where the high mutability of SVOD production processes meets the materiality of locations, sets and construction work, resulting in ‘logistical stress’. The chapter provides insights into how global media platforms influence local production cultures, labour practices and professional hierarchies in the streaming era, while considering impacts of geographic inequalities produced by the global platform economy.
