I don't think I saw this posted on here yet, but last night they released a new 2:31 minute Spiderman 3 trailer which was debuted on a couple of tv networks last night and also Ifilm.com. Here's a quick link to it -

I clicked on the 720p version of it for the full effect
I'm sooooo blown away by the trailer. I don't know how I'm gonna be able to wait until May to see it.
