Factual errors: As Piggy is short-sighted, his spectacles could not be used as a "magnifying glass" to light a bonfire: lenses for short-sightedness would scatter, not concentrate, the sun's rays. (This error occurs in the original novel.)

Revealing mistakes: During one of the signal fire scenes shot at dusk the fire can be seen burning in reverse, flames backing in towards the fire instead of shooting out from it.

Plot holes: Whatever happened to the large raft after they landed on the island?
