about the traps in the 4th Saw movie:
They're more thought out in this film, They're certainly gory, but in ways that you don't expect. They're more situational. We've got some big ones, some little ones, and a great surprise at the end."
"They're very specific, you can't just do anything. It's not just, 'How do we kill the guy?', it's 'How do we kill them really well?'"
Oren Koules (producer) stated that James Wan (director) almost fainted when he imagined one of the traps.
