IMDB...

Scanning the IMDB boards for "Spider-Man 3," I saw something..completely hilarious. The statement and question put forth by "Sexy-funny-lil-bugger":

"I was just watching the CC trailer in media player, and I noticed something.

At around 1:08 +, there are quite about 5 scenes conaining water (Sandman being washed away being the main one. However, after that, there is a man that appears wearing a blue t-shirt, and someone firing blue (water?) stuff out of there eyes).

Is this hydroman's work? Is he the forth villain? Please don't flame me, but if not, where is all the water from?"

The solution from "nestLEE":

"I swear the scene you're talking about is just a train going past sandman"

Amazing. Stay tuned..
