Prepare for the R-rated version of Batman v Superman: Dawn of Justice.

When the Zack Snyder film hits theaters on March 25, the clash between the Dark Knight and the Man of Steel will be PG-13, but when the extended version of the movie hits the home video market, it will include bonus scenes that have earned it an R from the Motion Picture Association of America.

The ratings board posted the news today, saying the “Ultimate Edition” includes more violence than the theatrical cut.

It’s unclear just how much bonus material will be added to the theatrical version, which runs 2 hours and 31 minutes. The R-rating may actually be a badge of honor, now that Fox’s Deadpool has turned into such a massive box office hit — partly for bushing the boundaries of sex, profanity, and brutality.

Most comic book films aim for the PG-13 designation, which gives it enough edge to satisfy adults, but allows more teenagers to attend without having sneak in or endure the humiliation of being accompanied by a parent of guardian. There isn’t the same risk when the R-rating is for the Blu-ray, DVD, or download, which don’t have theater ushers who are required to ask for identification.

Back in September, the ratings board gave the shorter version of Batman v Superman a PG-13 for “intense sequences of violence and action throughout, and some sensuality.” Warner Bros. didn’t immediately return a call for comment, but the idea that the fights could be even more savage and punishing is likely to be a decent selling point, rather than a drawback.
