Another year later, to commemorate the 20th anniversary of the film, MGM and 20th Century Fox Home Entertainment (whose parent company 20th Century Fox continues to hold all US rights to the film except for US home video rights) released the film with flippable cover art featuring the title displayed in an ambigram . This DVD did not include any of the bonus features from the older editions, but had new short featurettes and a new game. A Blu-ray Disc was released on March 17, 2009, encoded in DTS-HD Master Audio . Special features include two audio commentaries, the original theatrical trailer and eight featurettes. 
Westley, Inigo, and Fezzik invade the castle, and Humperdinck orders the wedding ceremony shortened. Inigo pursues Rugen through the castle. Rugen admits that he killed Inigo’s father, and they duel. Although Inigo is injured almost to defeat, his sense of revenge rekindles his energy and he kills Rugen. Westley reaches Buttercup, who has decided to commit suicide, and assures her that her marriage is a sham because in the shortened ceremony she never said “I do.” Still partly paralyzed, Westley bluffs his way out of a sword fight with Humperdinck, whom Buttercup then ties to a chair. As the party rides off on four white horses conveniently discovered by Fezzik, Westley offers the role of Dread Pirate Roberts to Inigo who, finding himself suddenly out of the revenge business, needs a new purpose in life.
