AMC Theaters is delaying its plan to start reopening its theaters by two-weeks. The nation's largest chain closed its theaters several months ago because of the coronavirus pandemic. The company announced Monday that it will open about 450 U.S. theaters on July 30th, and the other 150 the following week. The company operates the AMC Rivercenter 11 in San Antonio, and the AMC Classic Boerne 11 in Boerne.
