well, in all honesty it's got NOTHING to do with the first class, the first class faced off against magneto, not formed under him. At NO point was magneto on the x-men side(in 616...AoA is another kettle of fish entirely).

If it was really the first class we'd have Scott(still with that stick firmly lodged), Warren and Beast(not blue, or furry) working through college courses, Bobby being obnoxious and Jean being a bit of a tease. Then they'd face off against the Lensher Twins(unbeknownst to them), a very oddly dressed Toad and Magneto, king of the magenta!

So, yes, alternate reality, where Magnus wasn't ancient and pimpin' out his twins, and Charlie wasn't lusting after a youthful Ms. Grey.

And old movies never go away...just like old comics, they appreciate in value to discerning collectors ;)
