The Wolverine 3 Story and R-Rating Information Confirmed
According to separate reliable contacts, The Wolverine 3 has been targeting an R-rating since long before Deadpool’s stunning box office bow this past weekend. While that other X-Men spin-off movie grossing $132 million in three days is undoubtedly another great incentive to maintain the tone for The Wolverine 3, the filmmakers behind the mutant superhero film, including director James Mangold, have been planning for years to make a more violent farewell to Jackman’s beloved alter-ego due to the content of the “Old Man Logan” source material. While the MPAA of course makes the final determination of a film’s rating, the plan has always been to aim for an R.
Indeed, the “Old Man Logan” story by writer Mark Millar and artist Steve McNiven made waves due to its extreme nature when Marvel Comics published it between June 2008 and September 2009. Appearing in the pages of Wolverine #66-72 and Wolverine Giant-Size Old Man Logan, the grim tale takes place in an alternate universe and well into a distant, post-apocalyptic future. Within this dystopia, the United States has been taken over and divided by supervillains (and the Hulk). Magneto, Dr. Doom, and the Red Skull have split America amongst themselves after the mysterious end of the X-Men. And to make matters worse, now that Logan has a wife and two children, he refuses to unleash his claws or become “the Wolverine” again.
The comic book story is incredibly violent, featuring decapitations, brutal murders, and a hero who suffers from sudden bursts of bloodlust. It also showcases characters that are unlikely to appear in a 20th Century Fox film, such as the Hulk and Hawkeye. Nonetheless, Wolverine and the already announced return of Patrick Stewart as Professor Charles Xavier should be big enough news for X-Men movie fans.
