Trivia, insights & behind the scenes
Picha was a Belgian provocateur whose 'Tarzoon' got banned in UK; this was his slightly tamer follow-up. Spoiler-free context about Euro animation rebellion.
The brontosaurus mother was voiced by a man (Ron Venable) — the gender confusion is intentional and never addressed. Mild production oddity.
