Trivia: The song Angela Lansbury sings, "Little Yellow Bird," when she plays musical hall performer Emma, is the same song she sang in the 1945 film The Picture of Dorian Gray, when she played music hall performer Sybil Vane.
Trivia: Michael Mann was originally against casting Don Johnson. Prior to this TV series, Johnson had starred in four failed TV pilots.
Trivia: Aside from his considerable talent and theatrical qualifications, the reason that Jeremy Brett's portrayal of Sherlock Holmes was so nuanced, meticulous and authentic is because the role was therapeutic to him. In real life, all throughout the various Granada Television series (from 1984 to 1994), Brett was plagued with manic-depression, erratic behavior and heart problems, from which he fatalistically felt he would never recover. Immersing himself in the mentally-disciplined character of Sherlock Holmes gave Brett much-needed focus and clarity in the last ten years of his life.
