Its easy to see why Wolverine has become one of the most beloved characters in the Marvel universe: hes a gruff, no-nonsense brawler with a heart of gold (and a skeleton of adamantium). Theres also the fact that many of his storylines feature some extremely dark content as, even with the best intentions, Logan can often prove to be little more than a semi-tamed beast. Foxs previous attempts to bring Wolverine from page to screen have been a mixed bag of mostly poor decisions. The X-Men trilogy brought Hugh Jackman on board which has proved to the only thing that is consistently good about Logans portrayal on the big screen. Of the three, X-2 was the closest to the mark in terms of showing off Wolverines badass potential. While Logans most recent outing, The Wolverine, greatly improved on Foxs previous attempts there was still something missing; something which they are now wisely targeting for the third solo Wolverine movie: an R rating. Following the huge success of Deadpool, studios will be less reticent to put out superhero stories exclusively for an adult audience and this is great news for what seems set to be Jackmans last appearance as the ol Canucklehead. It seems to be a sure thing that the film will draw inspiration from the Old Man Logan arc but odds are they will also be looking to draw from other, darker tales of Wolverine. Whether its shocking moments from wider arcs or entire narratives which delve into his troubled psyche, it shouldnt be too difficult for Fox to give Logan his claws back.
