Kevin Daymude, general manager of Blockbuster Alaska, says the stores in Anchorage and Fairbanks will close for rentals after Sunday night.
The closures come just two months after the host of HBO's "Last Week Tonight with John Oliver" sent a jockstrap worn by Russell Crowe in the 2005 movie "Cinderella Man" to the Anchorage store, which displayed it in an effort to ramp up business.
Daymude says the buzz from the Oliver connection brought business to the store. But it wasn't enough to counter a planned lease increase.
The closures will leave the Blockbuster in Bend, Oregon, as the sole holdout.
