Which gets us back to the cameos of Cyclops and Storm (HA!). Why include the cameos if no one was asking for them? Especially if you know for a fact that showing said cameos will cause a fustercluck with your continuity! What gain did they get from that?
Lauren S-Donner actually gave the reason on the dvd. They added those cameos to show the fans that they (Fox and the producers) know the fans care about those characters, but since "they couldnt use them", they decided to show them as short cameos.
There u have it. Its Fox formula all over again.
This is how Fox works, since X3: lets add this character on X3 and this one and this one too, so the fans will be pleased, and we'll get more money.
Then on XO: Wolverine: hey, lets use young Scott, Emma, and lets use fan favourites Gambit and Deadpool, so more fans will go to theatre to see the prequel.
Then on FC, lets include a cameo of Scott and Storm, to surprise the fans and to show them that we care about them too, and we dont forget them, but they cant be used in full yet.
THIS is how Fox thinks, and this is how many decisions are made. Just to "please" fans and get "more" money.
And at the end of the day, ironically all those decisions ended hurting the movies.
Hopefully they wont do the same this time. Hopefully Millar does something positive to this franchise where the rest lacks.
