The background cast that comprise the background Others in scenes of the storyline from the 1970s appear to be drawn from a separate group from the background Others appearing in depictions of scenes from the "present" (approximately circa 2000 and afterwards). These extras were first depicted in Season 5 in "Whatever Happened, Happened". The 1970s Others extras are also used in scenes depicting events in the 1980s and 1990s. The exception may be possible overlaps in extras appearing in scenes from the Purge (approximately 1992). The extras used in the 1950s Others (appearing only in "Jughead") also appear to be a different group of people.
