The Return of the World's Greatest Detective

The Return of the World's Greatest Detective is a 1976 American made-for-television mystery comedy film starring Larry Hagman as an inept motorcycle cop named Sherman Holmes, who, after sustaining a head injury, became convinced that he was actually Sherlock Holmes and as a result of his injury acquired formidable powers of observation and deduction. Dean Hargrove and Roland Kibbee wrote the film's story directly for television, intending it to be a pilot for a series that would have been titled Alias Sherlock Holmes. The film originally aired on NBC on June 16, 1976.

The genres into which The Return of the World's Greatest Detective fits are comedy-drama and mystery-suspense.

Synopsis
Los Angeles Police Department officer Sherman Holmes (Hagman) is an inept motorcycle cop who cannot keep his police motorcycle from falling over on its side. He is lying on the ground, reading a copy of The Complete Sherlock Holmes, when his motorcycle again falls over on its side—but this time on his head, causing a cranial injury that leaves him comatose.

When he regains consciousness, Sherman Holmes has come to believe that he is actually Sherlock Holmes, the civilian consulting detective of literary renown. He also has acquired formidable powers of observation and deduction that he did not possess as a motorcycle officer. Holmes adopts the habits and mode of dress (houndtooth-gray Inverness cape, and "full-bent" meerschaum smoking pipe) of the literary detective, along with a stylized UK English dialect.

The social worker and psychiatrist assigned to work with Holmes is Dr. Joan Watson (Jenny O'Hara), the psychiatrist who had actually given Holmes the copy of the Sherlock Holmes "canon" in the first place. Her superior (Ivor Francis) warns that her job is at risk because of the situation. LAPD Detective Lt. Nicholas "Nick" Tinker (Nicholas Colasanto) is somewhat skeptical of what has happened to Holmes, but Watson points out that this Holmes wants anonymity as much as the literary Holmes did. She likewise arranges for him to move into Apartment 221B in an apartment complex located on Baker Street.

These strange occurrences take place at the same time of a case that has been baffling the LAPD: scandals that appear to involve a judge, the Honorable Clement Harley (Charles Macauley). Among these are the murder of an embezzler and a series of smoke-bombings. Holmes manages to solve both these cases—and expose an instance of judicial corruption in the process.

Partial production history
Dean Hargrove, who directed the film and jointly wrote and produced it with Roland Kibbee, loosely re-made the 1971 feature film They Might Be Giants in producing it. He and Kibbee both hoped it would become the pilot of a series titled Alias Sherlock Holmes, but NBC-TV declined to pick up that option.
