Stephen Baldwin sues Kevin Costner for Scheming him out of millionsKevin Costner and Stephen Baldwin aren't Harvard students weaseling inside a dorm room, they're grown men, but Costner allegedly pulled a 'Social Network'-style Zuckerberg move when he supposedly duped Baldwin into dropping his shares in Costner's company Ocean Therapy.

According to TMZ, Baldwin is suing Costner because he robbed him of his shares in the oil-filtering invention Costner sold during the BP oil leak disaster in the Gulf of Mexico.

According to a filed lawsuit in Louisiana federal court obtained by TMZ, Costner agreed to have Baldwin come on to his small biotech company, which built a device separating oil from water. The move assured Baldwin 10 percent of shares in the company. The key part of the lawsuit comes in Baldwin's accusation of Costner lying about plans to sell the devices to BP after buying Baldwin's shares back, when he later ended up selling 32 machines to the oil corporation. The deal with BP had an estimated value of $52 million.
