Jessica Alba, hot though she is, is no Susan Storm/Richards. Ioan Gruffyd, though a good actor, is no Reed Richards.
Everyone says that, but I think they were VERY well cast. Jessica was sweet when she needed to be but took Evans's Johnny down HARD when she needed to.
Ioan was the epitome of the good-hearted, somewhat absent-minded and a bit socially inept Reed Richards.
Furthermore, their chemistry together was spot on to the characters...unlike some I could name *cough*McGuire/Durnst*cough*...
See.. i didn't see ANY chemistry at all between them. Alba was cast because she's popular and has a good set of boobs and a nice ass (as evident by how she wore the uniform.. cleavage at its best and the "accident" where she ends up visible and naked). Gruffud because he made a good, younger Richards visually but that was it.. i wasn't convinced by his acting at all.
Chiklis and Evans though.. they had chemistry and were fun to watch and they were the closest to their comicbook characters (which is not always a good thing but here it fit).
The Fantastic Four movies were paint by numbers style movies.. marketing and "demographic research" people telling them who's hot right now and can bring in some of them "nerd" money by completely ignoring what made those comics popular in the first place and cast/write accordingly.
Case in point.. Dr. Doom. There is, i believe, not a single villain in the movies who's background was so totally destroyed with this movie and basically made a mockery of it. Doom in the comics is one of the best villains they have and he's appeared in numerous non-FF comics and he's just plain cool. Here he was a)miscast and b) totally uninteresting (how many times have we seen arrogant CEO types who look down on others and treat women as property and trophies?).
As i saw FF i thought to myself.. "Well.. that's it.. the streak has ended". Until that point Marvel, or rather the studios, had a lucky hand in choosing the production staff of the Marvel movies. Singer basically rebooted the entire genre with his X-Men movies after Batman & Robin sunk it, Raimi gave us excellent two Spiderman movies (the less said about the 3rd the better), Favreau with Iron Man etc..
All had one thing in common.. those responsible got what made the characters tick, they got their core and they built the story around it respecting it and treating it fairly.
Those movies that failed utterly (Elektra, FF) ignored it and paid the price.
I so hope they don't blow the next movies.. it will be easy to do. Cap America could be the walking US clichee with hammy one-liners and a "America Fuck Yeah" attitude and Thor has so many possibilities to be laughed at that chances are that they'll fail too (luckily the first iceberg has been missed.. they won't be using the fake Shakespearean language).
It remains to be seen what comes of it.. i was very sceptical when i heard Downey was chosen as Stark.. though i liked the actor before i just couldn't see him play the role. Then i saw the first picture and was amazed and when i saw him in the movie i was blown away.
I hope that these lightnings do strike twice, thrice or how many times they need to strike.. actors that fit the role perfectly and directors/producers who respect the origin and tell a good story.
If that happens and we get the Avengers movie it could be the blockbuster of the year. I wish them luck.
