August 3, 1966 –
Following the end of the series, Columbia Pictures released the animated film, The Man Called Flintstone, directed by William Hanna and Joseph Barbera and featuring the voice work of Alan Reed, Mel Blanc, Jean Vander Pyl, and Gerry Johnson, on this date.
This was the last Hanna-Barbera theatrical cartoon for Columbia Pictures, as well as the last after Hanna-Barbera productions stopped making theatrical cartoons while focusing on animated TV projects. In 1966, Hanna-Barbera was later acquired by Great American Broadcasting when the animation studio began producing their Saturday Morning cartoons.
