HBO chief executive Casey Bloys just confirmed that Warner Bros. is developing a possible movie spin-off of Game of Thrones. Bloys spoke at a press event on Tuesday, where he addressed the recent reports about a movie set in Westeros.

HBO is considering a 'Game of Thrones' movie, according to executive Casey Bloys. Scripts are being reviewed with author George R.R. Martin's involvement. Bloys emphasized the project's early stage, stating they are evaluating its cinematic viability.

HBO is indeed working on a Game of Thrones movie idea, but keep in mind that there's a big difference between "we have something in early development" and "this is definitely happening."
