I just saw this today when I saw "The Pursuit of Happyness". If you want to see it, it's the very first First Look so be at the theater at least a half an hour early. Or you can do what I did which was get there and hour early, just to be
SURE I didn't miss it. I actually got to see it twice cause I stayed in the theater to see the begining of the First Look again with the next showing. There was this really cool looking shot of Spidey webslinging at night with the crowd under him and the camera from the point of view of directly under him.( An animatic on this was in the leakied trailer) A closeup shot of Peter at the Spiderman day celebration looking proud and thankfull for the appreciation soaking in the moment. Mary Jane says an enthusiastic "Peter!" after she hugs him backstage. Brock saying something "battybattyfofatty, I came to see you!" flirting with Ms. Brant. I think teh shot of the symbiote covering the spider on Peter's chest and changing it looked different than it does in the trailer and improved. There was also the rest of the new stuff other people reported. Oh yeah, Peter says "I have this..." after J.J. tells him and Brock to get a picture of "Spider-man with his hand in the cookie jar". I must say that the footage looked great on the big screen even with the cinema lights still on.
I can't wait to see this movie!
