Michael Sheen Investigates Toxic Secrets in Wales

Michael Sheen is fronting a new BBC documentary titled "Buried (w/t)," which examines long-standing claims of chemical contamination in South Wales. This unscripted, two-part series is a personal endeavor for Sheen, who grew up in the affected region.

The documentary focuses on the late researcher Douglas Gowan, who had warned about "forever chemicals" buried in the land near farms and communities. Gowan believed these substances posed a lasting threat, but his warnings went unheeded before his death.

Sheen will meet with families, councillors, environmental journalists, forensic scientists, and medical experts. The aim is to seek answers about the area's toxic history and understand the responsibility communities and authorities hold for its future.
