Film With a couple of X-Men related films in release this year I've decided to rewatch the previous releases in the only potentially sane way which is Wolverine consciousness order as explained in this earlier post.
X-Men Origins: Wolverine
X-Men 3 (or whatever it's called in your end of the world)
X-Men: Days of Future Past
As I said at the time, this leaves out X-Men: First Class and which I'd decided to tuck in after Origins.
Having entirely forgotten about the Xavier cameo and the business with Emma Frost in Origins and that it's set in the 70s, I really should have begun with First Class.
Except of course that this means that the cliffhangers from the end of that film don't get resolved until Days of Future Past. Except that you can't watch that before X-Men because it's both prequel, sequel and wipes out that continuity anyway and also reconfigures some of the continuity from the earlier X-Men films itself anyway.
So the ideal place for First Class is probably between The Wolverine and DoFP.
Except, when exactly are the younger Wolverine sections supposed to be set in relation to the continuity in Origins?
This does offer a decent chronological attempt to deal with the timelines, although its deliberately short on detail. Essentially its meant to suggest that the Wolverine in DoFP has just left Stryker's team and is presumably on the run. Except Stryker's now being played by a much younger actor which is probably why in the character's biog the two events are switched around.
In other words, even though the Singer prequels have wiped the slate clean in terms of building the universe, thanks to Origins the whole business of watching the damn things in any kind of sensible order is still fucked.
Oh yes, I know, you could watch them in release order but with Origins released between X3 and The Wolverine, you're on a hiding to nothing.
In the end I've decided to watch First Class before DofP because ... shrugs.
