The upcoming “Game of Thrones” theater production “The Mad King” is still on track to open next month in the U.K. despite canceling its first week of previews, Variety can confirm.

The Royal Shakespeare Company production was set to launch previews Monday, July 20 but all four performances this week were canceled, disappointing a number of fans who traveled from afar, including overseas.

The play is taking place at the RSC’s homebase, the Royal Shakespeare Theatre in Stratford-upon-Avon, two hours outside of London.

A rep for the RSC declined to comment on what caused producers to pull the plug on the four preview performances, but confirmed Saturday’s show will go ahead as planned.

“We can confirm that the RSC and our co-producers took the difficult decision to cancel preview performances of George R. R. Martin’s ‘Game of Thrones: The Mad King’ this week, and that we are going ahead with the performance on Saturday 25 July,” the rep told Variety. “We can also confirm that the production will officially open on Saturday August 8.”
