Mulan's PG-13 rating makes it the first Disney live-action remake of animated classics to receive a rating above PG, and the first title from Disney's live action studio to receive PG-13 since Pirates of the Caribbean: Dead Men Tell No Tales in 2017.
Trailers have depicted Mulan as more of a fantasy war epic than a musical, which strays from Disney's remakes often following similar beats to the original films, plus or minus a few songs or characters. Yet with the rating signifying a slightly more grown-up tale of the Chinese legend, modern times have proved that PG-13 rated features can still play well for families.
