During the beginning of this film, actual original black-and-white archival footage is seen of the last ever Tasmanian Tiger living in captivity.
The Tasmanian Tiger, also known as the Tasmanian Wolf, thylacine or Thylacinus cynocephalus, the latter which is Greek for "dog-headed pouched one", is an extinct species of carnivorous marsupial. It is so called a Tasmanian Tiger because of the stripes on its back.
Approximately 40% of the film's production personnel were from Tasmania - Australia's small southernmost island where the film was shot. Locations included Maydena, Deloraine and the Florentine Valley.
When receiving the Honorary Golden Bear Award at Berlinale in 2018, Willem Dafoe chose this movie from all of his works to be screened as part of the ceremony.
Willem Dafoe had to deal with leeches during production filming in the Tasmanian wilderness in Australia. In a media interview, he joked how he didn't lose any blood, ironic because his previous Australian film Daybreakers (2009) had been a vampire movie. Both movies co-star Sam Neill.
