Gnomeo & Juliet: Sherlock Gnomes is a sequel to Gnomeo & Juliet. It was developed by Rocket Pictures. Andy Riley and Kevin Cecil wrote the script, Hamilton Shaw and David Furnish produced the film, and Elton John was the executive producer and composed the music for the film.
Garden gnomes begin disappearing mysteriously across England, so Gnomeo, Juliet, and their friends hire Sherlock Gnomes, "the greatest ornamental detective", who will help to try and solve the mystery of the disappearing gnomes. Unfortunately, however, Sherlock is not a good detective as his human counterpart, and soon the threat to the garden gnomes becomes even greater.
