While evil twins are inextricably linked to the soap opera (one particularly long-running "evil twin" soap opera storyline was on "All My Children", where David Canary played evil twin Adam Chandler and good twin Stuart Chandler for nearly 30 years), they have appeared in most televised genres. Some of the earliest usages were in fact in westerns. Two episodes entitled "Deadly Image" appeared within a year of each other on two different westerns. "Maverick's" version appeared in March 1961, followed swiftly by "The Rifleman's" take in February 1962. Beyond the coincidence of name, both offered similar plots: the hero becomes confused with a look-alike criminal, and the guilt of the hero must be cleared by demonstrating that the evil twin is a separate individual. "Pretty Little Liars" could be used as an example, where one of the main protagonists Spencer Hastings was discovered to have an evil identical twin sister named Alex Drake, who had been stalking Spencer and her friends under the identity of "A.D." for years.
