He's come to the rescue many times in films, and now actor Kevin Costner is hoping to rescue at least part of the environment.
BP is beginning to use the oil clean-up machines that Kevin Costner and his scientist brother designed. Costner testified before Congress last week about what his so-called Dream Machines can do. They use centrifugal force to separate the oil from the water.
BP has now ordered 32 of Costner's machines that the company will send out into the Gulf to help in the clean-up effort.
They've got a big job ahead. BP estimates that since the rig exploded two months ago, between 35,000 and 60,000 barrels of oil are flowing from the well every day. So far, BP has captured about 274,000 barrels of the leaking oil.
Costner estimates his machines will be able to clean up to 600,000 gallons of oily water a day.
