Donald Jeffries can really get a person to think about things. Especially the Paul_is_dead urban legend that started between 1966 and 1967.

"According to Tony Barrow, who wrote about it in his book "John, Paul, George, Ringo and me," the rumours about McCartney's death started circulating in September 1966.[1] At the time, Barrow was the press officer for the Beatles and was responsible for fielding calls from fans and the media. He began receiving a number of dubious calls from people asking about whether Paul was alright, but he denied those claims due to the fact he claimed to have called Paul. In early 1967, a similar rumour circulated in London that Paul McCartney had been killed in a traffic accident while driving along the M1 motorway on 7 January.[2] The rumour was acknowledged and rebutted in the February issue of The Beatles Book." https://en.wikipedia.org/wiki/Paul_is_dead#Beginnings
The movie Seconds was released in the fall of 1966 and over the subsequent years, the Paul_is_dead urban legend grew. Did the movie Seconds provide some of the motivation to create this urban legend?

How could such an urban legend be created with several interesting clues? Of course the biggest part of it was the implication that Paul McCartney was replaced.

Indeed, the Mission:_Impossible_TV_series would occasionally use impersonation masks.
"Certain team members, as masters of disguise, impersonate the target or someone connected to the target using realistic latex face masks and make-up. A few early season episodes showed the painstaking creation and application of these masks, usually by Rollin Hand. This was later omitted as the audience presumably became familiar with the team's methods. In the 1980s revival, the mask-making process involved a digital camera and computer, and was mostly automatic. In most cases, the guest star would play the role of both the original and the agent-imposter (ostensibly Rollin, Paris, or Casey). Some impersonations are done with the explicit cooperation of the person being impersonated. In some cases, the same actor playing the IMF agent also portrayed the person to be impersonated; this most frequently occurred during Martin Landau's tenure on the series, notably in the pilot, or supplied the voice of the person being impersonated by dubbing. Most episodes included a dramatic "reveal" (also referred to as the "peel-off") near the end of the episode in which the team member would remove the mask.
Bona fides would be created to aid infiltration of the target government or organization. Various other technological methods were used, as well. Telephone or radio calls were often rerouted so the team could answer them. Faked radio or television broadcasts are common, as are elevators placed under the team's control. In some missions, a very elaborate simulated setting is created, such as a fake train or plane journey, submarine voyage, aftermath of a major disaster, or even the take over of the United States by a foreign government. In a particularly elaborate ploy, used on more than one occasion, the IMF convinces their target that several years had passed while the target was in a coma or suffering from amnesia. In another instance, the IMF even convinced its target, an aging mobster (played by William Shatner) that time has somehow been turned back more than 30 years and he is a young man again." https://en.wikipedia.org/wiki/Mission:_Impossible_(1966_TV_series)#Plan
