Though BP’s Deepwater Horizon oil spill in the Gulf has prompted investigations of the disaster itself and who’s to blame, we’ve reported that over the past decade BP’s own internal investigations  warned that the company was risking major accidents by disregarding safety and environmental rules.

That broader narrative, which stretches from BP’s oil fields in Alaska to its refineries in Texas and to its trading rooms in New York and London, is detailed in a new documentary called “The Spill,” produced in partnership by Frontline and ProPublica.

Through interviews with current and former employees and executives, government regulators, and safety experts, the documentary retraces the company’s tracks leading up to the fatal Gulf disaster and asks whether such an accident could have been prevented.

“The Spill” airs on October 26 at 9 pm ET—check your local listings. Catch a glimpse in the promo:
