This book offers tools to address the growing and urgent interest in exposing and challenging unconscious biases in the studio, exploiting how actor training uniquely combines elements of education and culture. It is the first practical and rigorous investigation of Pierre Bourdieu’s idea that domination and inequality are embodied in surreptitious ways.This book adapts and develops the techniques of Joan Littlewood and Ariane Mnouchkine that juxtapose the social with the comedic to theatricalise Bourdieusian concepts, inviting critical consciousness and critical praxis in the studio. It constructs the creative intervention Ludic Activism that can be practically applied in an actor training context. Actors from diverse training backgrounds were trained to use Ludic Activism, co-investigating how the Bourdieu-inspired vocabulary and pedagogy can facilitate the acknowledgement and tackling of dispositions during theatre-making. Ludic Activism developed the participants’ social representations into progressive and compassionate versions, reinforcing an understanding and use of their positionality in performance through a set of authorial acting tasks.This book is an advanced study for actors, directors, and teachers of acting for both the training/rehearsal studio and research.The methodology, account of the process, and evaluation of the creative intervention – including illustrations and selected videos that can be accessed on the Routledge website, under the Support Material section, here: https://www.routledge.com/Bourdieu-in-the-Studio-Decolonising-and-Decentering-Actor-Training-Through/Stamatiou/p/book/9781032306070 – demonstrate a decolonising and decentering trajectory for actor training.
