Richard Corliss noted that the film appeared to have been influenced by "The Wizard of Oz" and the works of Maurice Sendak, writing, ""Labyrinth" lures a modern Dorothy Gale out of the drab Kansas of real life into a land where the wild things are." Nina Darnton wrote that the plot of Labyrinth "is very similar to "Outside Over There" by Mr. Sendak, in which 9-year-old Ida's baby sister is stolen by the goblins". This almost got the film into legal trouble, as the similarity caused Sendak's lawyers to advise Jim Henson to stop production on the film. However, the legal complaint was eventually settled, with an end credit being added that states, "Jim Henson acknowledges his debt to the works of Maurice Sendak." Sendak's "Outside Over There" and "Where the Wild Things Are" are shown briefly in Sarah's room at the start of the film, along with copies of "Alice in Wonderland", "The Wizard of Oz", and "Grimms' Fairy Tales".
