Michael Sheen Investigates Wales' Toxic Legacy in New BBC Documentary

other · 2026-08-11

Actor Michael Sheen delves into the hazardous legacy of industrial chemical disposal in Wales in a BBC iPlayer documentary. His focus is on locations highlighted by the late researcher Douglas Gowan, who claimed that Monsanto had released significant quantities of industrial chemicals, including PCBs, throughout Wales. Gowan identified 14 sites, 12 of which are in Wales, before his passing. Sheen, who conversed with Gowan prior to his death, has pursued the investigation further. The film includes Michael Phillips, diagnosed with rare cancer after playing near a Wrexham lagoon, and reveals Sheen's blood tests that detected 81 types of PCBs. It also discusses a fire at Llwyneinion lagoon in the 1980s and associated cleanup expenses. "Buried with Michael Sheen" premieres on BBC Two and iPlayer on 17 August at 21:00 BST.
