The film:
- Box Office Bomb: Had a budget of $25-30 million, but a revenue of only $3.8 million.
- California Doubling: Takes place in the Smoky Mountains, but was shot in the Czech Republic.
- Casting Gag: In the Japanese dub, the titular Serena is voiced by Nana Mizuki, who already voiced another crazed, homicidal Yandere before.
- Fake American:
- Buchanan is played by David Dencik, who is Swedish-Danish.
- Galloway is played by Welsh Rhys Ifans.
- Rachel Hermann is played by Ana Ularu, who is Romanian.
- Troubled Production: Despite being shot in only a few months in 2012 (right after Lawrence and Cooper had finished Silver Linings Playbook) and there were no reshoots or major problems
in post-production, apart from Bier taking time off to promote her other film, Love Is All You Need, it was a year and a half before it premiered at the BFI London Film Festival and another six months before it was given a limited theatrical release.
