Harryhausen next made First Men in the Moon (1964), his only film made in the 2.35:1 widescreen (AKA "CinemaScope") format, based on the novel by H. G. Wells. Jason, and First Men in the Moon were box office disappointments at the time of their original theatrical release. That, plus changes of management at Columbia Pictures, resulted in his contract with Columbia Picture not being renewed. Also, as the 1960s counter-culture came to influence more and more and younger filmmakers, and failing studios struggled to find material that was popular with the new "Boomer-generation" audience, Harryhausen's love of the past, setting his stories in ancient fantasy worlds or previous centuries, kept him from keeping pace with changing tastes in the 1960s. Only a handful of Harryhausen's features have been set in then-present time, and none in the Future. As this revolution in the traditional Hollywood movie studio system, and the influx of a new generation of film makers sorted itself out, Harryhausen became a free agent.
