Warner Bros. animators, under the leadership of Charles M. “Chuck” Jones, launched their own, albeit mild, counter attack when they introduced Marvin the Martian in 1948, several years before The Manchurian Candidate (1962), Fail Safe (1964), Seven Days in May (1964), Dr. Strangelove (1964), or Boris and Natasha, the Russian spies in the Rocky and Bullwinkle cartoons of the late 1950s and early 1960s.
