A production of *Game of Thrones: The Mad King* is set to open in London in 2027, following an announcement by George R.R. Martin. Both outlets report that the show is moving to a London staging for the 2027 date.

The reports also say the news comes after a prior run that has been sold out. The coverage frames the London engagement as the next step for the production, built on audience demand demonstrated by that earlier success. While details of the original venue or the specifics of the sold-out engagement are not expanded in the provided excerpts, both sources present the 2027 London run as confirmed.

Overall, the outlets align on the central points: the title, Martin’s role in confirming the release, the 2027 timing, and the location being London. Differences, where present in the excerpts, are mainly in wording rather than in substance, with one emphasizing the opening in London and the other describing the confirmation as a “new” 2027 release.
