Writer/Director James Mangold said 'Logan' needed to be an R-Rated movie.
Mangold was speaking about the film at the 2018 Writers Guild Association Beyond Words panel.
Mangold spoke about why the mature tone of the story dictated the rating.
For Mangold, it was about not having to write the film for 11-year olds.
"If we had a rated-R movie there were gonna be no Happy Meals. There can be no action figures. There was gonna be no marketing on Saturday morning cartoons or anything like it, so that suddenly you?re not making a movie written for someone under 14, 15."
'Logan' is available on Blu-Ray and DVD now.
