In Peter Jackson's film adaptation of The Lord of the Rings, Mount Doom was represented by two active volcanoes in New Zealand: Mount Ngauruhoe and Mount Ruapehu. In long shots, the mountain is either a large model or a CGI effect, or a combination. The production was not permitted to film the summit of Ngauruhoe because the Māori hold it to be sacred, but some scenes on the slopes of Mount Doom were filmed on the slopes of Ruapehu.
