What does collaboration in Dutch inclusive theatres look like, and what key themes can be identified? Data were collected through interviews and co-creative sessions with seven independent theatre makers and members of three participating theatre groups (n=48). Thematic analysis resulted in the proposal of a model that identifies six interconnected core issues central to inclusive theatre practices: the Atomium Model in which dynamic tensions of attracting and repelling forces exist. The study concludes that those involved in inclusive theatre are willing to continuously face artistic and collaborative challenges to fulfil their political ambitions and to dismantle prejudices and barriers. Plain language abstract: We studied the collaboration between theatre makers, actors with and without intellectual disabilities, and coaches in inclusive theatres in the Netherlands. We spoke with seven independent theatre makers and participants from three inclusive theatre groups and organised co-creation sessions. Through this research, we identified six interconnected themes that are essential to collaboration within inclusive theatre practices. These themes are characterised by inherent tensions, such as the balance between pushing personal boundaries for growth and respecting them for safety. We concluded that participants in inclusive theatre continually face artistic and collaborative challenges to achieve their ambition of dismantling prejudices and barriers.
