LONDON (AP) — Some of London’s biggest West End shows, including “Hamilton” and “The Phantom of the Opera,” won’t reopen until next year, producers announced Wednesday, as arts bodies warned that Britain faces a “cultural catastrophe” because of the coronavirus pandemic.

Producer Cameron Mackintosh, his producing partners and his Delfont Mackintosh Theatres group said “Hamilton,” “The Phantom of the Opera,” Mary Poppins” and “Les Miserables,” would return “as early as practical in 2021.”

The company said it was talking to staff about “potential redundancies.”

Mackintosh, one of Britain’s biggest and wealthiest theater producers, said the decision was “heartbreaking” and criticized Prime Minister Boris Johnson’s government for offering stage producers ”no tangible practical support beyond offers to go into debt, which I don’t want to do."

He said the government’s “inability to say when the impossible constraints of social distancing will be lifted makes it equally impossible for us to properly plan for whatever the new future is.”

Music, theater, art, design, architecture and publishing generate billions for the British economy each year, but the country’s clubs, theaters, cinemas, concert halls and art galleries shut down in March as part of a nationwide lockdown to slow the spread of the coronavirus.

Shops and outdoor spaces such as zoos are now starting to reopen, but indoor venues remain closed because of social distancing rules that require people to remain two meters (6 ½ feet) apart.

The government says it's reviewing the distance rule amid pressure retailers, restaurateurs and others to cut it to one meter (three feet).

A study released Wednesday by research firm Oxford Economics projected that the U.K.’s creative industries could lose 74 billion pounds ($93 million) in revenue this year and a fifth of the U.K.’s 2 million creative-sector jobs could disappear.

Chief executive Caroline Norbury of the Creative Industries Federation, which lobbies for arts and culture, said that “without additional government support, we are heading for a cultural catastrophe.”

“Thousands of world-leading creative businesses are set to close their doors, hundreds of thousands of jobs will be lost and billions will be lost to our economy," she said.

Norbury and other culture-sector leaders called on the government to set up a “cultural renewal fund” and continue support programs that have supported self-employed people and furloughed workers during the lockdown. The Treasury plans to scale back the programs in the next few months.
