Commentators have drawn parallels between '' Captain Scarlet '' and the Cold War . Media historian Nicholas J. Cull interprets the " war of nerves " between Earth and Mars as a reflection of strained international relations during the 1960s and likens the " enemy within " scenario of Martians taking over humans to the plots of films like '' Invasion of the Body Snatchers '' ( 1956 ) . Mark Bould states that '' Captain Scarlet '' " seemed in tune with a decade of civil disobedience and anti-imperialist guerrilla wars " – a view echoed by Rebecca Feasey of the University of Edinburgh , who writes that it is one of a number of TV series that " exploited the fears of 1960s America by presenting civil disobedience and the potentially negative impact of new technologies . " Since 2001 , comparisons have also been made to the September 11 attacks and the ensuing War on Terror
