X-3 was crap.
20th century fox killed off the best characters so that Marvel studios could not continue to make x-men movies.
Everyone knew that Marvel was opening their own production studios, so 20th century made a preemptive strike so that Marvel could not move forward wit any more x-men movies.
The beauty of comics are Alternate Realities.
Just because someone else made a flik does not mean you can't re-make one that is better.
If they do it right, they will follow the same route they took with LoTR and film a trilogy in one shot, then break it up appropriately.
I think the Phoenix Saga (Starjammers et all) would be a great one to do, and do right.
Of course, a bit of modernization would be needed to correct some eggregious out-dating (Scott's Swashbuckler Dad, for instance...)...
This flik looks like it has possibilities, but they have already (seemingly) made Magneto too young. Banshee and the rest were young adults at the time of this in comic time (late 70's?) Magneto was a 9/10 year old in Nazi Germany (avoided being killed in a concentration camp by moving the bullets around him when standing in a firing line). 1940 -> 1975 = 35 years... Mag had to be at least 45 in this if they are going back to the original time.....
Anyway, I hope they get it right. They have the screenplay already written for them, why do they think they need to change it so much all the time?
