  ===Untitled ''Game of Thrones'' spin-offs===
  In May 2017, after years of speculation about possible successor series, HBO commissioned Max Borenstein, Jane Goldman, Brian Helgeland, Carly Wray and Bryan Cogman to develop individual ''Game of Thrones'' successor series; all of the writers were to be working individually with George R. R. Martin, who also co-wrote two of the scripts. On June 8, 2018, HBO commissioned a pilot to a ''Game of Thrones'' prequel series from Goldman as showrunner and Martin as co-creator. S. J. Clarkson will direct and executive produce the pilot, which is scheduled to begin filming in mid-2019 in Northern Ireland and other locations.
