NEW YORK -- Hollywood's hopes for salvaging its summer season have effectively ended after the releases of both Christopher Nolan's 鈥淭enet鈥 and the Walt Disney Co.'s live-action reboot of 鈥淢ulan鈥 were again delayed.

With reported cases of the coronavirus surging in parts of the U.S., Disney on Friday followed Warner Bros. in pushing 鈥淢ulan鈥 to late August. The film, initially planned to open in March, had been slated for July 24. It's now moving to Aug. 21.

鈥淲hile the pandemic has changed our release plans for `Mulan' and we will continue to be flexible as conditions require, it has not changed our belief in the power of this film and its message of hope and perseverance,鈥 said Disney co-chairmen Alan Horn and Alan Bergman in a joint statement.

Late Thursday, Warner Bros. also postponed 鈥淭enet,鈥 starring John David Washington and Robert Pattinson, from July 31 to Aug. 12. The studio stressed the need for flexibility.

鈥淲e are choosing to open the movie mid-week to allow audiences to discover the film in their own time, and we plan to play longer, over an extended play period far beyond the norm, to develop a very different yet successful release strategy,鈥 a Warner Bros. spokesperson said in a statement.

Movie theatre chains had planned the widespread reopening of cinemas partially around the return of new releases like 鈥淭enet鈥 and Disney's 鈥淢ulan.鈥 AMC Theaters, Regal Cinemas and Cinemark - the three largest circuits in North America - had all set a timetable for nationwide reopening in early to mid-July with the aim of first playing catalogue movies (including Nolan's own 鈥淚nception鈥) and a smattering of smaller films as a lead-in to summer tentpoles.

But with COVID-19 cases surging in Texas, Arizona, Florida and elsewhere, those plans became uncertain. Rising cases in California forced Disney earlier this week to delay next month's planned reopening of Disneyland in Anaheim. On Wednesday, New York Gov. Andrew Cuomo also said New York would delay reopening cinemas while it continued to research the safety of indoor, air-conditioned venues.

United Artists Releasing's 鈥淏ill & Ted Face the Music鈥 also pushed back from Aug. 14 to Aug. 28.
