If you know anything about the X-Men franchise, there are quite a few popular X-Men characters that are actually fairly recent creations compared to other Marvel franchises. Deadpool, Cable and X-Force, for example, were created in the late 80's/early 90's, and all three are slated to get movies soon. Characters like X-23 were created after Fox signed the movie deal (and who knows? A female Wolverine movie might be a potential (stupid) idea that they go with). New characters aren't completely worthless.
LOL how is 25 + years ago recent? that was the rise of their heyday. The "recent" xmen are at best forgettable , you can drop names all you want, none of those characters have anywhere near the fanbase as the blue / gold (xmen)/xfactor/new mutant days. Xforce was ultimately canceled and lived on THRU the xmen titles. With the original team being distributed across *SHOCK* the uncanny xmen, xfactor, and the new mutants.
There hasn't been an off the hook "Xforce" book featuring Boom boom, Cable, Deadpool, Feral, Domino, Shatterstar and whoever else was on that scrub team for over a decade....maybe two.
X 23 was created in Xmen Evolution the cartoon I wonder what her status is , not that marvel would use her.
The only xman in that list that we KNOW is getting a movie is again, from the tried and true Blue team of Xmen, Gambit.
Xforce, Deadpool, insert knew shit mutant from Gen X to New Xmen, have ALL been "getting movies" for some time now, i think people will care when they can buy a ticket.
