This study explores the potential of digital twins as a collaborative platform connecting municipal stakeholders and the film industry in Trollhättan, Sweden, a city renowned for its prolific film production. Despite its cinematic output, “Trollywood” has not capitalized on film-related tourism due to the lack of on-location filming. The research leverages the ""Invest Trollhättan 2022 - 2030"" initiatives to examine how digital twins can align with the film industry's priorities and encourage a participatory development approach. The study will address potential challenges in developing a joint digital twin and explore how such tools and technology can support diverse stakeholder needs effectively, thereby enriching the dialogue around popular culture tourism, virtual meta-tourism, and digital twin applications. 

It aims to understand how film-related tools within digital twins can streamline processes like filming permits and boost the locale's attractiveness by integrating visual narratives from film production as part of popular culture into the urban development strategy and for destination marketing for both the film industry and for tourism in general. 

The methodology centers on empirical data colleted from workshops with film industry stakeholders and film enthusiasts scheduled for early summer 2024 in Trollhättan. 

The theoretical underpinning of the study is rooted in co-creation, participatory design, and on-screen tourism, aiming to meld stakeholder engagement with destination and placemaking strategies to deepen immersion and widen participation in urban development in a digital world. 

Anticipated results include insights into the integration of a digital twin into existing urban fabrics. The outcomes are expected to inform a collaborative digital twinning framework, positioning it as a tool for stakeholder-oriented urban development and placemaking.
