Released on Netflix in the US within weeks of the theatrical release of another Mads Mikkelsen-led movie Arctic (2018) which happened to be titled 'Polar' in some international territories. The two movies are unrelated.
The cabin where Vanessa Hudgens's character lives is the same as the one from I Heard a Rumor (2019). The back travelling shot of the last scene is almost the same as the one used in that episode.
A full, high-quality copy of the movie was leaked online nearly a week ahead of the official release date on Netflix.
Instead of the end credits using the normal bottom to top crawl, they start at the top and crawl down.
