This is one of the earliest examples of a crossover (characters from different stories meeting and interacting with each other) in anime. In this case, characters from Osamu Tezuka's manga comics are put together in a unique situation.
The film takes place in 2002.
While Osamu Tezuka oversaw the production of this feature, most of the animation was drawn by assistants, but Tezuka insisted on personally drawing every cel of Black Jack.
Mami Koyama's debut.
