Inside the story of Sayonara Jupiter
Sayonara Jupiter centers on a premise that unfolds like this: In the 22nd century, scientists from an energy-depleted Earth research new fuel sources in the far corners of the solar system, where they discover an ancient alien race from Jupiter as well as the emergence of an apocalyptically dangerous black hole. Koji Hashimoto's 1983 sci-fi adventure was conceived as a Japanese competitor to the upcoming sequel to Stanley Kubrick's classic 2001, titled 2010, and often mirrors the sequel's plot.
Rather than rushing, the film lets tension build naturally, trusting the audience to keep up. The tagline — "A black hole, Jupiter and a desperate scheme to save mankind!" — captures that tone perfectly.
