This paper examines the phenomenon of creative collaboration building on the ethnographic case of TV screenwriting writers’ rooms. Moving beyond the conventional focus on creative outputs, this article explores how the experience of ‘being together’ shapes the collaborative process. The study adopts a process phenomenological perspective, drawing on the work of Merleau-Ponty, to investigate the dynamic interplay of embodied, spatiotemporal, and vulnerably co-present dynamics. We develop the concept of ‘creative togetherness’ as a lens to analyze the relational dynamics inherent to creation processes in groups. The findings reveal three interconnected peak experiences of creative togetherness: ‘mingling,’ characterized by a tension between excitement and tiredness, which lays the groundwork for creative possibilities; ‘sketching,’ marked by oscillations between engagement and distraction, which shapes possibility spaces through embodied resonance; and ‘composing,’ where the interaction of stress and release intensifies the collaborative process as groups move toward a shared outcome. The paper argues that creative togetherness marked by the interplay of the three peak experiences constitutes an immersive sphere of relatedness that sheds light on how the material and affective dimensions of communalization maintain creative momentum within collaborative settings.
