A Disney movie, but unlike any other Disney movie you've seen.
A bit of a trope plot, where a mad but brilliant scientist is enchanted by a force more powerful than him (The Black Hole), and faced opposition from the crew who discovers him. Borrows from Forbidden Planet, with special effects obviously inspired by Star Wars.
Beautifully shot with wonderful visuals. The acting is a bit weak, and the plot a little weaker. There's still something charming about this movie that stands the test of time.
