The science of cryogenics is a wonderful thing beloved by those who believe they will somehow be revived from the dead in the years to come. The slight practical obstacle that no one has yet succeeded in such an enterprise in real life does not deter film makers from using it as a plot device when they need to move characters across intersteller space or move them through time. Despite refrigeration being a a little primitive in the 1890s, Holmes has been frozen and revived on more than one occasion, most recently in Sherlock Holmes in the 22nd Century.

A cryogenically frozen Holmes is discovered by Watson's great grandaughter.
