hmmm the Silver Surfer. This is from total memory. First of all his name is Norrin Rand (or some such, but like I said this is from total memory). He was the greatest scientist of a super advanced world (maybe the most advanced in the Marvel Universe), but even they could not stop this "plague like thingy) from killing them
-- OR--
He was the greatest scientist of a super advanced world (maybe the most advanced in the Marvel Universe) but they could not stop Galactus*. Thus he made a deal with the Devil & in return Galactus would spare his world (which he later welched on, I think).
Any way thus SS was
litteraly created by the Hand of Galactus. As the SS, Norrin rode the Power Cosmic for what seemed like an eternity until of course he found hte good ole' Earth & thus our pending 2nd movie franchise entry.
Now if they stick with the Marvel story as written then is is not so much as a fight against the FF per se, but a moral thingamajob against Mr. Fantastic in particular. Now this could be the start of a SS movie franchise of his own, because Reed Richards is gonna make (again, this is the original Marvel story) one of the most Fantastic (sorry) Statements Ever in the Marvel Universe at the end of this movie.
Also, I hope this is NOT like the Star Trek franchise, where you have to keep all the Treks separate, because the Incredible Hulk has a major, major, major role in this story. Suffice it to say, seeing a realistic rendition of the Hulk bending the Surfers' board would be worth the price of admission alone, IMHO.
I have been waiting since like 1980 something for this movie. I will be able to die a happy man

* Galactus in the Marvel Universe is not so much a being, but rather a quasi-mystical force, like say Death or Gea. He/it is bound to the Multiverse in such a way, that if his role of World-Eater went unfulfilled (sorry) then all kinds of things would be thrown out of wack
