Disney's The Little Mermaid may be the best-known animated film based on Hans Christian Andersen's short story, but it was by no means the first. This Russian film, directed by Ivan Aksenchuk in 1968, uses a variety of animation styles to capture the sad tone of the tragic fairy tale, from the horrors of the mermaid's promise to the price she's willing to pay to preserve her love's life.
