The Deepwater Horizon oil rig is seen burning in April 2010. A second phase of the BP trial started this week looks at just how much oil spilled into the Gulf of Mexico.
This Sunday marks four years since the BP Deepwater Horizon oil rig exploded -- killing eleven people and spewing 4.9 million barrels of oil into the Gulf of Mexico.
Earlier this week, BP announced it has ended "active cleanup" of the spill.
But a new documentary called "Vanishing Pearls" shows that for many living in the region -- the effects of the incident linger on. We're joined now by the film's director Nailah Jefferson.
