If you believe everything you hear on the comic book grapevine, the third and final Wolverine movie will go by the title Weapon X. And if, like me, you're a bit of an X-Men fanboy, you've probably spent at least a few minutes mentally dissecting what that could mean for Hugh Jackman's final outing as Logan.
Will we see a more-or-less direct adaptation of the comic of the same name, or something more along the lines of a hybrid with another classic story? I'm inclined to think Weapon X might combine three of Logan's most iconic comic book arcs: its namesake, Old Man Logan and Death of Wolverine.
A problem with the Weapon X arc is that we see Logan mostly viewed through the prism of three scientists working on the programme. Despite the fact that their experiments are responsible for him, it's hard not to feel a tinge of pity for three regular guys faced with the threat of an animalistic human weapon driven by rage and confusion.
Given that this movie has been described as feeling tonally like a Western, it's hard to imagine how the more visceral, horror-esque Weapon X could be ripped straight from the page, but it could quite easily serve as an origin in the opening act of the film (yes, we're just going to pretend a certain other movie never happened).
What we do know, thanks to a little tease from X-Men producer Simon Kinberg, is that the movie is set in the future. We also know that Patrick Stewart will return as Professor X for the first time since Days of Future Past. Does the choice of time period hint at the possibility of Old Man Logan being adapted?
The most beloved Wolverine comic arc of all sees the USA transformed into an unrecognizable, post-apocalyptic wasteland, ruled by supervillains such as Red Skull (who's now President) and Doom. Logan is one of the last heroes standing, only he hasn't sharpened his claws for quite some time.
Reluctantly, he agrees to accompany his friend Hawkeye on a mission, which doesn't exactly go to plan. You can read more about why Old Man Logan is such a winner right here.
The casting of Boyd Holbrook has a "calculating head of security for a global enterprise" doesn't sound like it would mesh entirely with the premise of Old Man Logan. That character bio feels less post-apocalyptic wasteland and more high-tech future dystopia, which might open the door to the possibility that the movie will borrow from Death of Wolverine.
Like the name suggests, the Death of Wolverine arc was the final bow for a man who'd suffered far more than any man should over decades of comic book history. It acutely captured the nature of a character who exists in far too grey an area to be labelled simply hero or villain, tortured by his own origins and by an outside world obsessed with the Wolverine.
All of which would make it an ideal cinematic send-off for one of Marvel's great anti-heroes. Apologies if you read this article expecting a definitive answer on what, but that's knowledge nobody has, unless you want to hack Simon Kinberg's cloud. (I do not endorse that idea.)
