I can't wait for this movie, but like you all, I'm really concerned about everything, from start to finish. On whether we'll get to see the Hulk before the first trailer, I personally hope not. In fact, I would love it if they showed us as little of the Hulk as possible for as long as possible. Mainly to keep us in suspense, but here are my reasons in full:
1.) I think they need to be as serious as a heart attack in getting this second rendition of the Hulk right - much in the same manner Batman Begins was taken so seriously to exorcise its past demons. I think we're off to a great start with Zak Penn writing the script (Note to Zak: I loved X3), but even having picked up Ed Norton, I'm concerned that the loss of continuity with the first film already has TIH at a disadvantage. Not only are we starting fresh, it's like we're asking the general public to give the Hulk a second chance, which doesn't seem good. We don't want to be begging people for their attention, I reason - the movie should have a natural appeal about it that incites within them their own desire to see it. Thus, I feel the less the Hulk is shown, the better, because it prolongs (or helps to re-establish) an intrigue factor with people. In the months leading up to TIH, I think we want them asking, "Why is this Hulk is so different from the one before?" and "Why should I take my kid out to see it when the first one wasn't that great?" Bottom line: There has to be some element of surprise, but if we're inundated with images of the Hulk all over the place before the movie has been shown - and then the cat is immediately let out of the bag in the teaser - then I'm afraid the Hulk loses one of his biggest draws and that is what he actually looks like.
2.) Having said all of that, let's face it, the Hulk's size and color are two of his two most identifiable traits. There's no concealing the fact he's huge and green, and we do want people to have some familiarity/comfort with the Hulk... but I say we use this piece of information to our advantage and only slightly reveal him in the teaser and subsequent trailers, if possible. I reason the biggest unknown about the Hulk is his strength and THAT is what I think Marvel needs to exploit, if anything. My ideal teaser goes something like this:
With Abomination (or whatever he's named in the movie) threatening all of existence, the situation on earth is dire - of catastrophic proportions. We desperately need someone or some thing to save us, and only the Hulk is qualified for the task. Hulk, being on the run, is pulled away from his attempts to find a cure and drawn back into the ring, so to speak. The key is the desire HAS to come from within, so as to provide contrast to the enormous battles he's facing inside - to save himself or to save humanity. His decision, and ultimately the hope of mankind, is revealed only at the end of the trailer with a glimpse of the Hulk facing off against Abomination. Show a furrowed eyebrow and a low rumble, then bring the camera out slowly to a full-body side rear view, at about knee level... a magnificent display of Hulk's back musculature and anger brimming as he glares at Abomination across from him in a misty or well-lit setting (not sure which is better). Signal a monumental roar just as Hulk pounces upon Abomination, then cut to the title screen: "All Fury Is Unleashed - The Incredible Hulk - In theaters June 13, 2008"
That's how I think it should go anyway. Fostering an urgency within people is of utmost importance in my mind. The Hulk himself is huge, so the story has to be even bigger. If the producers play this lightly and try to create a more "likable" Hulk - with more battle sequences, as we've heard - I think we lose. One to two incredibly well designed battles should do it. And not to be overly formulaic, but I think they need to play up the love story with Betty. Think about Spider-Man. He has amazing superpowers, yes, but isn't it the love story with Mary Jane and his nerdiness that makes his story so much more relatable? The more superheroes are distanced from us (i.e. Superman, an alien whose only weakness is Cryptonite), the less we can relate to them, I feel. As hard as it may be, I think the Hulk needs to be brought to eye level with viewers; I'm just not sure that accomplishing this in the trailers is the way to go.
