<P> The 1981 BBC The Lord of the Rings radio play has "The Scouring of the Shire" story included, during which the Shire homeland is taken over by ruffians . Like the events of the book, Frodo, Sam, Merry, and Pippin rally the Hobbits to fight against the ruffians . Ultimately, the Hobbits win The Battle of Bywater . The radio play includes the original showdown and ending in which Saruman dies by Wormtongue's knife and Wormtongue is killed by arrows in the Shire . It also tells about the murder of Lotho, and Lobelia Sackville - Baggins gives Frodo and Sam back his home and money to help out the Hobbits . She later dies of old age . Then Frodo, Sam, Merry, Pippin, and the Hobbits clean up the Shire and restore it to normal . This is included in the last episode, The Grey Havens . </P> <P> The events of the Scouring of the Shire are retold in the Finnish miniseries Hobitit </P> <P> By contrast, the events of "The Scouring of the Shire" do not occur in any film adaptation of the novel to date . It is not featured in the 1980 animated version of The Return of the King and only alluded to in the 2000s The Lord of the Rings film trilogy, in which the Mirror of Galadriel shows an invasion of the Shire by Orcs as something that has not yet come to pass . Galadriel tells Frodo that this is a glimpse into a future that has not yet been decided, but, should he fail in his quest to destroy the One Ring, the events depicted in the Mirror will come to pass . Consequently, when the hobbits return home in The Lord of the Rings: The Return of the King, the Shire is unchanged . In the extended edition of The Lord of the Rings: The Return of the King, Wormtongue kills Saruman (through stabbing him in the back, not slitting his throat) and is in turn killed by arrow as in the novel; however this takes place at Isengard instead of the Shire and it is Legolas who shoots Wormtongue . </P>
