West End hits The Lion King and The Life of Pi are among a number of shows that have been forced to cancel performances due to Covid-19 outbreaks.
The Lion King called off shows on Tuesday and Wednesday due “to Covid-enforced absences” among cast and crew.
The Life of Pi also had to scrap five performances between 9 and 13 December.
The Royal Shakespeare Company’s Comedy of Errors at the Barbican in London has also cancelled all performances until 22 December due to Covid cases.
The company said scrapping performances “was a last resort”.
The National Theatre had to scratch Monday’s preview of its Christmas show Hex after one of its lead actors caught Covid. The play, based on Sleeping Beauty, has now postponed its press night from Wednesday to 21 December.
In a letter to critics, artistic director Rufus Norris wrote: “You will no doubt be aware of the impact that Covid has been having on productions across the industry (none of ours over the last year have escaped entirely) but the impact on Hex has been considerable, with several members of the company including one of our leads being taken ill during the technical and preview period, and fresh bad news on that front again today.”
