The Great Mouse Detective (1986)

Based on the children's book series Basil of Baker Street by Eve Titus, it draws heavily on the tradition of Sherlock Holmes with a heroic mouse who consciously emulates the detective; Titus named the main character after actor Basil Rathbone, who is best remembered for playing Holmes in film (and whose voice, sampled from a 1966 reading of "The Adventure of the Red-Headed League" was the voice of Holmes in this film, 19 years after his death). Interestingly, Sherlock Holmes also mentions "Basil" as one of his aliases in the Arthur Conan Doyle story "The Adventure of Black Peter".
