The Big Fix is a 2012 documentary film about two filmmakers as they travel along the coast of the Gulf of Mexico, meeting the residents whose lives were changed by the 2010 BP Oil Spill. The Big Fix was the only US documentary chosen as an Official Selection at the Cannes Film Festival in 2011.
This is an excellent movie on BP and the oil spill. Below is the official website of the documentary & a trailer for the film. While the website doesn’t truly give you a sense of what the documentary is actually about, trust me: it is really good.
