Special Edition, Spaceballs and A Nightmare on Elm Street all contain the commentary from the laserdisc release. This may be for financial reasons, depending on whether the rights to the original commentary are cheaper to use than recording a new one (a company releasing a film on DVD today may not be the same company who released it on laserdisc); or it could simply be that the original commentary does its job well without the need for an update. Contrastingly, some DVDs do not have a commentary even though the laserdisc release did (for example, Taxi Driver). This may be because the parties involved have not reached a publication agreement. The audio commentaries of The Criterion Collection are often considered some of the finest and most informative commentaries ever made, and the Laserdisc releases of classic films can be highly priced because Criterion generally did not license their commentaries for use on later DVDs when the rights to films they have release revert to the studio, including the aforementioned Taxi Driver. But commentaries like that now appear on the Blu-ray versions of films. Other notables include the commentary for The Silence of the Lambs (featuring stars Jodie Foster and Anthony Hopkins, along with director Jonathan Demme) and Terry Gilliam's tracks for The Adventures of Baron Munchausen and The Fisher King. In addition, the fact that Criterion have been commissioning commentaries since 1984 means that commentaries exist by film makers who died before the advent of DVD, such as Michael Powell. Commentary exclusive to LaserDisc Some commentaries that were issued on Laserdisc have not been reissued or replaced on DVD. Sometimes this is because there was a deluxe LD edition while there has only been a bare bones release on DVD, for example The Fisher King. In the case of the first three James Bond movies, Dr. No, From Russia with Love, and Goldfinger, the commentary was once released on LaserDisc but quickly judged inappropriate, never to return (new commentary tracks are on the DVD editions). The commentaries are available to download at The 007 Dossier. Video games Some video games, such as the episodic sequels to Half-Life 2 and Tomb Raider: Anniversary, have experimented with audio commentaries. Unlike DVD commentaries, the systems used for video games do not use a predetermined continuous flow of speech, because the events of a game depend on the player's actions. Instead, in-game prompts are
