This Kirby Atkins(The Ant Bully, Jimmy Neutron) project has been brewing for many years and had previously shown up as a teaser “Beast of Burden” in 2015 and it looks like it’s done and working it’s way though distribution. There is an English teaser trailer but this Czechoslovakian one shows much more of the upright thoriphants.
The film tells the story of Mosley, a “thoriphant” who rebels against his life of servitude and embarks on a treacherous journey to find the fabled city of Uprights.
