After the success of last year’s animated hit film Teenage Mutant Ninja Turtles: Mutant Mayhem, Paramount Pictures is keeping turtle power going by putting a new feature project into development.

This one, however, will go beyond the realm of the all-ages material the long-standing property is known for and instead go into gritty, R-rated, territory.

Paramount is developing Teenage Mutant Ninja Turtles: The Last Ronin, adapting a popular storyline seen in the recent IDW comics, as a live-action feature with the intent of making it for an R-rating.

Tyler Burton Smith, who co-wrote the upcoming R-rated action movie Boy Kills World and who wrote the 2019 iteration of Chucky horror franchise Child’s Play, is penning the script.
