Trivia :

• Premiere : 11/28/1986
• Frej Lindqvist and Anders Nyström (voices of Basil and Dr. Dawson) also voiced Sherlock Holmes and Dr. Watson.
• For the second DVD release, the reprise of "Good Bye So Soon" during the credits used an instrumental version. This is due to the 5.1 remix Disney used for this release. The Swedish vocals are available on all other releases.
