While we can usually assume a box office flop that killed an animation studio would be a total letdown, one hidden sci-fi animated gem has earned a reputation as a cult classic. Telling the story of humanity trying to survive the destruction of Earth in the vast recesses of space, this star-studded sci-fi mixed hand-drawn and computer-generated imagery to tell a thrilling story that never quite got its due from mainstream viewers. Originally envisioned as a live-action sci-fi for adults, the unusual production history of this 20th Century Fox meant it failed to reach an appropriate audience.
