The question of Black Widow‘s rating has been solved, and it’ll obviously be PG-13 like all other MCU movies.
Kevin Feige shot down the R-Rated rumor with ComicBook today, when asked about the rumor of the movie being rated R:
“It never was going to be,” Feige said. “Somebody writes, ‘I hear it’s R-rated!’ And then everybody writes it up.”
So there it is from the head of Marvel Studios, Black Widow will not release with an R rating.
