"Childe Rowland" is a fairy tale, the most popular version written by Joseph Jacobs in his "English Fairy Tales", published in 1890.
 It was based on a Scottish ballad, which is why the text alternates between prose and rhyming stanzas.
 Joseph Jacobs called the King of Elfland's palace "the Dark Tower" in his version, an addition he made that was not part of the original ballad.
 This harks to Shakespeare's "King Lear" and Robert Browning's poem "Childe Roland to the Dark Tower Came," but neither of those references have any relation to the fairy tale.
The Tale of the Fisherman and the Fish (Russian: Сказка о рыбаке и рыбке , "Skazka o rybake i rybke") is a fairy tale in verse by Alexander Pushkin.
 Pushkin wrote the tale in autumn 1833 and it was first published in the literary magazine "Biblioteka dlya chteniya" in May 1835.
 The tale is about a fisherman who manages to catch a "Golden Fish" which promises to fulfill any wish of his in exchange for its freedom.
 The storyline is similar to the Russian fairy tale "The Greedy Old Wife" (according to Vladimir Propp) and the Brothers Grimm's tale "The Fisherman and His Wife".

 The tales are completely Andersen's invention, owe no debt to folk or fairy lore, and are the most autobiographical of his several fairy tale collections.

The British film-making partnership of Michael Powell (1905–1990) and Emeric Pressburger (1902–1988)—together often known as The Archers, the name of their production company—made a series of influential films in the 1940s and 1950s.
 —24 films between 1939 and 1972—were mainly derived from original stories by Pressburger with the script written by both Pressburger & Powell.
 Powell did most of the directing while Pressburger did most of the work of the producer and also assisted with the editing, especially the way the music was used.
 Unusually, the pair shared a writer-director-producer credit for most of their films.
 The best known of these are "The Life and Death of Colonel Blimp" (1943), "A Canterbury Tale" (1944), "A Matter of Life and Death" (1946), "Black Narcissus" (1947), "The Red Shoes" (1948), and "The Tales of Hoffmann" (1951).

 The libretto was written by the composer, and is based on a Russian fairy tale about Koschei the Deathless, an evil, ugly old wizard, who menaced principally young women.
 A similar fairy tale was also used by Igor Stravinsky (Rimsky-Korsakov's pupil) and Michel Fokine to create their iconic ballet, "The Firebird".

 It is a striking unusual tale, with few variants, and often appearing more mythological than is common for fairy tales.
 It was collected by Mrs. Balfour from the North Lincolnshire Carrs in the Ancholme Valley; its unusual characteristics made many people doubt its origins as a fairy tale.
 However, when Mrs. Balfour published her notes, they were generally found reliable, and the Fens proved to have many other unusual legends.
 The story may be evidence of moon worship.
