A federal lawsuit filed Wednesday in New Orleans by Baldwin and a friend claims Costner and a business partner duped them out of their shares of an $18 million deal for BP to buy oil-separating centrifuges from a company they formed after the April 20 spill.
BP ordered 32 of the centrifuges, which separate oil from water, and deployed a few of the devices on a barge in June.
Costner's publicist, Arnold Robinson, declined to comment Thursday on the suit's allegations.
The lawsuit seeks unspecified damages.
