Spiral: From the Book of Saw

Detective Ezekiel 'Zeke' Banks (Chris Rock, who inspired the idea for the film) and his partner (Max Minghella, The Social Network) find themselves at the centre of a new sadistic killer's evil game in the ninth installment of the Saw franchise. Samuel L. Jackson co-stars as police veteran Marcus Banks.

According to Rock - an avid Saw fan - a chance meeting with Lionsgate head Joe Drake while at a friend's wedding lead to him pitching an idea for a new Saw film and expressing his interest in being involved in the franchise.
