A significant percentage of R-rated dramas would earn more at the box office with a PG-13 rating, The Hollywood Reporter reported Tuesday.
Those findings come from a study that compared the box-office performances of 400 R-rated and PG-13 films released between September 2005 and December 2007.
Nielsen's analysis found that 34% of all R-rated drama titles would have performed better with a PG-13 rating, while about 17% of all comedies would benefit from a less restrictive rating.
In contrast, few horror movies would have achieved higher gross earnings with a PG-13 rating, according to the study.
