World Without End

Edward Bernds · 80 minutes

Four astronauts returning from man's first mission to Mars enter a time warp and crash on a 26th-century Earth devastated by atomic war. At first unaware where they are, but finding the atmosphere safe to breathe, they start exploring and find themselves in a divided future where disfigured mutants living like cavemen inhabit the surface, while the normals live comfortably below the surface but are dying as a race from lack of natural water, air and sunlight.

How Titan works

Titan combines the archive’s quality, audience and legacy base with the significance of time travel. It is an index, not a score out of 100, and is distinct from the FMV archive’s scoring model.

Titan = base × [0.20 + 0.80 × (time-travel score ÷ 10)²]

This film: 60.08 base × 48.8% weighting.

Partial inputs flag incomplete source metadata. Provisional weighting flags a time-travel assessment that remains uncertain; it receives no additional confidence penalty.
