Two of animator Chuck Jones more interesting cartoons that are unlike anything he did for Warner Brothers.
The Dover Boys at Pimento University or The Rivals of Roquefort Hall is one of his funniest cartoons. A spoof of The Rover Boys series of books about some morally upright young lads whose fiancee Dainty Dora Standpipe is kidnapped by the evil Dan Blackslide.
The animation is more stylized than usual for a Warner's cartoon. This is a spoof of a boys own adventure series like The Hardy Boys or Nancy Drew. Very different from the typical Merrie Melodie cartoons that Warners was producing. What really counts is that The Dover Boys at Pimento University or The Rivals of Roquefort Hall is hilarious.
Hell Bent for Election is a campaign film that Jones made for the presidential campaign of 1944. It's amazing how much of the same liberal vs conservative stuff is still being argued about even today. The film was made at the early incarnation of the UPA group, the animation studio that specialized in stylized and minimalist backgrounds. This is an excellent example of using film as a piece of propaganda.
Hell Bent for Election lays out its point of view very effectively using the metaphor of the modern democratic and rickety republican trains in a race to see who will win the presidential election.
