Re: Hulk ad ?
The movie ad was scheduled to premier on the Super Bowl, and undoubtedly afterwards it would have shown up on the movie web site, as these things normally do. Unfortunately, somebody at their office must have put it on the web site early, and some fanboy searching around for cool stuff found it before the site was supposed to be made public. So the ad, which undoubtedly set the movie company back a good chunk of cash to get it premiered on the Super Bowl, is now spread all over the Internet.
Whoever put it on the server early to save hassle is probably in trouble.
