Trivia: The "Bride in Black" is played by a man wearing women's clothing. This was done so that something would feel "off" about the image of the ghost. At the time, the character was intended to be female. However, when the creators later reused the character for the sequel and added in a backstory, they worked the fact that the character was played by a male as part of his backstory - it actually is a man who masqueraded as a woman as a disguise to lure in victims.
Trivia: Makeup artist Rick Baker has a cameo appearance in this film. He's the man who whistles to his comrades who are approaching the gypsy camp then a few seconds later, gets killed by the werewolf.
Trivia: Like Tanedra Howard won a role in Saw 6, Gabby West won the second season of Scream Queens and is featured in this film. She is Kara, Evan's girlfriend. She is underneath one of the rear wheels of the car in the garage trap.
Trivia: In the opening scene with Richard Dreyfuss fishing on the lake he is singing to himself "show me the way to go home". This is a nod to the movie Jaws because it is the song that he sang along with the rest of the crew as they waited for the tagged shark to be re-sighted. (00:01:00)
Trivia: When Nancy is drowning in the blood, the blood breaks through the floor to pour into the bedroom downstairs. This is a tribute to the original's famous bed-death scene where Johnny Depp is slaughtered by Freddy, causing the room to be drenched in his blood. (01:23:30)
Trivia: The first film Wes Craven both wrote and directed since the release of "New Nightmare" 16 years earlier. It was also the final film Craven both wrote and directed before he tragically passed away. (While he did direct "Scream 4" the following year, he was not a credited writer on it).

Trivia: Originally, Kevin Greutert, who edited the first five "Saw" movies and also directed "Saw VI" and "Saw 3D," was attached to direct. However, Lionsgate enacted a contractual clause to remove him from the film. While an exact reason was never given, it has been widely speculated that this was done because the "Paranormal Activity" movies were the only direct competition for the "Saw" series at the box office.
