The director and one of the stars of a new documentary film about the Biosphere 2 experiment, which saw eight researchers sealed into a manmade ecosystem for two years, are the latest guests on Sir Tim Smit’s series of webinar conversations.

Matt Wolf, the director of the Spaceship Earth documentary, and Kathelin Gray, a director of the Biosphere 2 project and contributor to the film, will join Eden Project co-founder Sir Tim in his latest Kitchen Table Conversation at 6pm on Sunday (August 9).

Sir Tim, Matt and Kathelin will discuss the film, the legacy of the Biosphere 2 experiment, its influence on the Eden Project and its relevance to a world emerging from the Covid-19 pandemic.

Sir Tim said: "Biosphere 2 is a complete inspiration to me and it will go down in history as an important milestone for the environmental movement. I'm looking forward to discussing the incredible story behind the project with Matt and Kathelin on Sunday."

Spaceship Earth is the true, stranger-than-fiction, adventure of eight visionaries who in 1991 spent two years quarantined inside of a self-engineered replica of Earth’s ecosystem called Biosphere 2.

The experiment was a worldwide phenomenon, chronicling daily existence in the face of life-threatening ecological disaster and a growing criticism that it was nothing more than a cult. The bizarre story is both a cautionary tale and a hopeful lesson of how a small group of dreamers can potentially reimagine a new world.

The conversation with Matt and Kathelin is the third in the series of webinars, which began with a conversation with Eden trustee and author Jonathan Drori CBE ( and continued with marine social scientist and Eden Ambassador Dr Easkey Britton (
