Trivia, insights & behind the scenes
Loopy De Loop was Hanna-Barbera's only theatrical short series starring an anthropomorphic wolf with an accent and a heart of gold.
This 7-minute Jekyll & Hyde parody arrived the same year as the Hammer Horror classic, proving 1961 couldn't escape Stevenson's shadow.
