Production Notes

When the film was release in the UK in 1969, the BBFC imposed some cuts, but there are no details as to what those cuts were – it's likely that they were in the scene where the dinosaur attacks the elephant.

In the USA some local TV stations have been known to remove the in which Gwangi attacks and kills an elephant on the grounds of animal cruelty.
