High definition versions of Pan's Labyrinth were released in December 2007 on both Blu-ray Disc and HD DVD formats. New Line stated that due to their announcement of supporting Blu-ray exclusively, thus dropping HD DVD support with immediate effect, Pan's Labyrinth would be the only HD DVD release for the studio, and would be discontinued after current stock was depleted. Both versions had a PiP commentary while web extras were exclusive to the HD DVD version. In October 2016, The Criterion Collection re-released the movie on Blu-ray in the US, based on a newly graded 2K digital master supervised by Del Toro. An Ultra HD Blu-ray edition of the film is scheduled for release in 2019 by Warner Bros. Home Entertainment remastered for 4K.
