I tracked down these two videos that some took at Comic Con. Sadly, embedding is disabled so you'll need to go here to see part 1 and here for part 2.
After watching this, I'm wondering where in the heck some of the reporters get off repeatedly talking about Zombies and the army of the undead even though Jimmy Hayward clearly said that wasn't in the movie.
The video does get a little tiresome with the constant fawning over Megan Fox. I'm thinking she may be the downfall of the film.
