Today the MPAA issued its weekly CARA Ratings Bulletin today, as they do every Tuesday, and they have just rated a R-Rated version of Wonder Woman for “some violence”, however this looks like it isn’t the 2017 live action movie.
If you look at the bulletin it lists a 2009 date for the original PG-13 rating, which would mean this is for the animated movie and not the 2017 one out in June:
The animated Wonder Woman was actually really good, and written by Gail Simone who has a history with the character in the comics. Will the R-Rating be worth a double-dip of the title before the live action movie is released? That will depend on how much is added.
