Marking Time – Tam Gilbert’s Artistic Project

Directed by Tam Gilbert, written by Mandy Redvers-Rowe and created by a visually impaired team, Marking Time is a gritty, politically-driven new play exploring the realities of prison life through the story of visually impaired Paralympian and activist, Jeff. As time passes inside his cell, and independence becomes negotiation, Jeff’s memories surface, revealing the moments that shaped the man behind the bars.
Through vivid flashbacks, the play moves between Jeff’s attempts to navigate his new environment, the charged emotion of his first Extinction Rebellion protest and the intensity of elite sport, from the discipline of training to the determination required to compete in a world that expects you to fail.
Marking Time is an urgent and deeply human story about freedom, resilience and the cost of standing up for what you believe in. This new play lays bare the emotional toll of navigating an environment that was never designed with blind or visually impaired people in mind.
Content warning: This play contains strong language, graphic threats of sexual violence and explores themes of barriers and isolation in prison, which some audience members may find upsetting.
