A series of still images put together to create the illusion of movement
Otherwise known as animation. See Anomalisa.
The use of this phrase stems from the interview with Charlie Kaufman and animator Duke Johnson for the stop-motion animated film, "Anomalisa", which aired on 5 March, 2016. Johnson, as part of his response to Mark's question about the technical production aspects of the film, explained "it's just a series of static images creating the illusion of movement, over time." The obviousness of this statement, inasmuch as it applies not only to animation but to all cinema, combined with the sombre, humorless and seemingly somewhat reticent demeanour of Kaufman, resulted in the "static images" line being repeated as a supposedly revelatory insight on several other films.
