A look-alike, double, or doppelgänger is a person who bears a strong physical resemblance to another person, excluding cases like twins and other instances of family resemblance. Some look-alikes have been notable individuals in their own right, such as Britain's King George V and Russia's Tsar Nicholas II, who bore a striking resemblance to each other (they were first cousins). Other notable look-alikes have been notable solely for resembling well-known individuals, such as Clifton James, who acted as a double for British Field Marshal Bernard Montgomery during World War II. Some look-alikes who have resembled celebrities have worked as entertainers, impersonating them on stage and screen, or at venues like parties and corporate functions. Professional look-alikes have often been represented by talent agencies specializing in celebrity impersonators. Close physical resemblance between two or more individuals is also a common plot point in works of fiction. Cousins, Britain's King George V (1865–1936) and Russia's Tsar Nicholas II (1868–1918), shared an uncanny resemblance. Their facial features were only different up close (especially the eyes). At George's wedding in 1893, according to The Times of London, the crowd may have confused Nicholas with George, because their beards and dress made them look alike. An urban legend claims that Charlie Chaplin entered one of the many Chaplin look-alike contests and lost. It is retold in the musical Chaplin. Mikheil Gelovani, a Georgian actor and Joseph Stalin look-alike, played the Soviet leader in propaganda films of the 1930s and 1940s. In 1944, shortly before D-Day, M. E. Clifton James, who bore a close resemblance to Field Marshal Bernard Montgomery, was sent to Gibraltar and North Africa, in order to deceive the Germans about the location of the upcoming invasion. This story was the subject of a book and film, I Was Monty's Double. A notable conspiracy theory holds that Paul McCartney died in 1966 and was replaced by a Canadian policeman named William Shears Campbell.
