Actor Kevin Costner, center, leaves Federal Court for a lunch break in New Orleans, Monday, June 4, 2012. Stephen Baldwin has sued fellow actor Costner over their investments in a device that BP used in trying to clean up the massive Gulf of Mexico oil spill. The federal lawsuit filed in New Orleans on Wednesday 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 purchase oil-separating centrifuges from a company they formed after the April 20 spill.
