NATIONWIDE -- AMC Theatres, the largest movie theater chain in the world, has pushed back the reopening of its U.S.-based movie theaters once again.

The company announced Thursday that it now plans to reopen its theaters in "mid to late August." Previously, the company's U.S. locations were prepping to reopen around July 30.

"This new timing reflects currently expected release dates for much anticipated blockbusters like Warner Bros.' Tenet and Disney's Mulan, as well as release dates for several other new movies coming to AMC's big screens," the company said in a news release.

Earlier in the week, Warner Bros. removed Tenet from its release calendar and has yet to announce a new date. Mulan was delayed indefinitely on Thursday, with Disney removing the live-action remake from its release calendar. 

Regal Cinemas, the second-largest movie theater chain, and Cinemark have also delayed their reopenings. 

Regal was set to reopen its theaters at the end of this month. The company's website has been updated with a message that says, "announcement of new reopening date coming soon." 

Meanwhile, Cinemark, has shifted the reopening timeline for its theaters, with no new date given. The chain originally planned to reopen most of its theaters Friday with a lineup of classic films.

“The company continues to evaluate availability of new studios content, status of the virus and local government regulations as it plans for the phased reopening of its U.S. theaters,” a Cinemark spokesperson said in a statement to Spectrum News.

Movie theater chains have been hit hard by the pandemic, which caused them to close locations in mid-March. But reopening theaters in the U.S. has proven difficult as coronavirus cases surge in large states like California, Texas, and Florida.

Previously, AMC, Regal, and Cinemark announced they would implement new health and safety measures at their theaters, including requiring visitors to wear face masks, reducing capacity in auditoriums, and increasing cleaning throughout its facilities.
