It was expected that Batman v Superman: Dawn of Justice would get a PG-13 rating (the equivalent of a 12A here in the UK), but the reason for it is rather surprising.
According to the MPAA, Batman v Superman: Dawn of Justice has been awarded a PG-13 rating for, “intense sequences of violence and action throughout, and some sensuality.” Sensuality, eh? Wonder where that might come from…
So, we can expect the movie to get a 12A here in the UK from the BBFC.
Batman v Superman: Dawn of Justice is set for release on March 25th 2016 and sees Zack Snyder directing a cast that includes returning Man of Steel stars Henry Cavill (Superman), Amy Adams (Lois Lane), Diane Lane (Martha Kent), Laurence Fishburne (Perry White), Harry Lennix (General Swanwick), Michael Shannon (General Zod) and Christina Wren (Carrie Farris) alongside Ben Affleck (Argo) as Batman, Gal Gadot (Fast & Furious 6) as Wonder Woman, Jason Momoa (Game of Thrones) as Aquaman, Ray Fisher as Cyborg, Jesse Eisenberg (Now You See Me) as Lex Luthor, Jeremy Irons (The Borgias) as Alfred Pennyworth, Holly Hunter (The Piano) as Senator Finch, Tao Okamoto (The Wolverine) as Mercy Graves, Jeffrey Dean Morgan (Watchmen) as Thomas Wayne and Jena Malone (Sucker Punch), Callan Mulvey (300: Rise of an Empire), and Scoot McNairy (Argo) in as-yet-unrevealed roles.
