Pretty Slick reveals the untold story of BP's coverup following the 2010 Deepwater Horizon oil explosion in the Gulf of Mexico. The explosion is known as one of the largest environmental catastrophes in the history of the United States, but what is not well-known is that BP, along with government approval, used toxic chemicals to sink the oil in the water rather than clean it up, using a controversial chemical dispersant called Corexit. Because of this, it is estimated that approximately 75% of the oil, or over 150 million gallons, is still unaccounted for. When filmmaker James Fox learned of this, he began a three year investigation to find out about the dispersant use and its coverup. Pretty Slick reveals how public safety and environmental health took a backseat to restoring the economy, and along the way exposes the collusion between big oil and the United States government in these happenings.
