Previously rated R by the MPAA for "bloody horror violence, language and some sexuality."
The story on which the film is based, "The Bridge to Body Island," has a much more complex mythology for the Bye Bye Man: He was an albino born in New Orleans in 1912 who ran away as a child and became a derelict who lived in a train yard. After going blind he began murdering people and cutting out their eyes and tongues, which he sewed together and brought to life using voodoo. The resultant creature became the Bye Bye Man's literal seeing-eye dog, helping him hunt his prey. Several elements from the story- notably the dog and the motif of trains-- were retained for the movie, though their purpose is left more elliptical.
Filmed in November and December 2015, but not released until January 2017.
Cressida Bonas's acting was so bad that during a screening of the film, the entire audience laughed whenever she was on screen and said anything.
Doug Jones, who plays the title character, previously played Slender Man (who has similar abilities) in Always Watching: A Marble Hornets Story.
