Trivia / The Seven-Per-Cent Solution

• Creative Differences: Nicholas Meyer revealed that he had often fought with Herbert Ross because Ross was too faithful to Meyer's novel. He believed that the script would not be cinematic enough if it was too faithful with the source.
• Fake Brit: Robert Duvall as Dr. Watson.
• Fake Nationality:
  • Alan Arkin as Sigmund Freud.
  • The Czech-born Gertan Klauber as The Pasha.
  • Joel Grey as Lowenstein.
• Self-Adaptation: Nicholas Meyer adapted his own novel.
• What Could Have Been:
  • The part of Mycroft Holmes was originally offered to Orson Welles.
  • Charlotte Rampling was considered for Mary Watson.
  • Bernard Herrmann was slated to compose this score but died the December before the film was completed. He had gone as far as to suggest to Herbert Ross a musical beginning where, as the credits roll, the camera slowly dollies toward a performing orchestra, eventually finishing with a closeup of Holmes as one of the violinists. Herrmann's idea was to imply this is what Holmes did during his absence. Ross chose to use a different start.
    • Meyer himself later used this idea in The Canary Trainer, with Holmes playing violin in the Paris Opera orchestra during the Great Hiatus.
