- Banned in China: Almost got a +18 rating in France.
- Bilingual Bonus: Even though the movie is supposed to take place in France, a francophone can tell that most of the actors are Quebecers passing as French people.
- Completely Different Title:
- Estonia: Witnesses
- Turkey: Torture Chamber
- Creator Breakdown: The movie's screenwriter, Pascal Laugier, has stated he wrote the screenplay while in a state of clinical depression, bordering on suicidal thoughts, and it really shows.
- The Foreign Subtitle:
- Poland: Martyrs: Doomed to Fear
- Old Shame: The American remake was this for Blumhouse Productions, the production company behind the film. According to Bloodbath & Beyond, the Blumhouse Productions usually promote their own movies on their official website (which also acts as a news site for horror genre), but the one movie that they did not promote was the Martyrs remake they financed and produced. Not even a trailer, photo stills, poster nor press kits were posted on their website — as if they are distancing themselves away from the movie.
