Dinotopia is a four-hour (three-episode) TV miniseries co-produced by Walt Disney Television and Hallmark Entertainment. It is based on the fictional world of Dinotopia, a utopia in which sentient dinosaurs and humans coexist, created by American author James Gurney. The miniseries uses plot details from Gurney's first two Dinotopia books, Dinotopia and Dinotopia: The World Beneath, although it takes place in a time farther into the future. The main characters are two American teenage boys from a contemporary time frame (unlike the Victorian era castaways in the books—the film thus loses some of the classicism of the original books). The boys crash their father's plane into the sea and get stranded on Dinotopia, where they must adjust to a new society. The story in the film contains references to many of the characters in the book series, with some of their descendants occupying key roles in the plot. The original score was composed by Trevor Jones. This score is performed by the London Symphony Orchestra, conducted by Geoffrey Alexander.
