- Actor Allusion: Tariq is mentioned as being a documentary filmmaker played by actual filmmaker Ti West.
- Actor-Shared Background:
- Approval of God: Adam Wingard actually sent out a supportive tweet for a Couch Gag video which mixes the movie and The Simpsons.
- Creator Cameo: While more of a extended cameo, the writer of the film, Simon Barrett, plays one of the three masked killers, Tiger Face.
- The Shelf of Movie Languishment: The film had its premiere in 2011, which led to a bidding war over the domestic rights (Lionsgate won with a $6 million bid). The studio then proceeded to sit on the film for two years after a bad test screening (which led people to wonder if the film would ever open). Finally, it was released in 2013.
- What Could Have Been: Before the movie bombed at the box office, a sequel was considered where Erin would be part of a chain gang and taking on the cousins of the original movie's killers.
- The ending originally involved Erin being killed by a police officer who shot her in the head.
