William B. Doeren, senior vice president and chief operating officer of AMC Entertainment Inc., resigned from the company “to pursue other interests,” the company said in a statement. The Kansas City, Mo.-based movie theater circuit, the largest independent operator in the country with 1,600 screens, did not give a reason for Doeren’s resignation.
