The star of the recent History Channel Show the "Hatfields and McCoys" is in a feud with another actor.

The drama between Kevin Costner and Stephen Baldwin started unfolding with a jury selection in a New Orleans court room Monday morning.

Baldwin and another former business partner, Spyridon Contogouris, are suing for $21 million dollars in damages.

They say Costner left them out of a business meeting with BP in which the oil company agreed to make an $18 million deposit for 32 of Costner's oil cleanup devices.

Baldwin an Contogouris sold their shares of the company marketing the devices before the deal with BP.
