Junk Head
If Jan Švankmajer were Japanese and considered making something like Sexmission, it might have resulted in a film similar to Junk Head. This animated piece by debutant Takahide Hori is a feature-length expansion of the sci-fi short of the same name, which takes us into a post-apocalyptic future. In it, mankind has finally achieved its longed-for immortality through genetic experimentation. But it has paid the price in fertility, and now faces extinction. The solution may lie in a small underground civilization of clones who broke free from humans long ago and seem to be able to bring forth little baby clones. The human government therefore sends a scout to their weird world to find out how things really are and, consequently, save the human race.
