Oops, sorry I was sent this email and thought it was from that person sending but this is apparently from imdb.
on imdb had this to say:
So we just got back from the Q and A and it was rather crazy. The organizers of the event did well with security but when it was time for Rob to come on stage they were having so much trouble with the audio. The mics kept sending feedback and we could barely here what they were saying.
When Rob walked out the screaming was intense as expected. But he was genuinely shocked because the way the Galleria is set up, there were fans looking down into the venue from all three floors. He had this really cute look of horror on his face.
It was really awesome seeing him come out on stage but I felt so bad for him when it was time for the questions. We literally could not understand a single word because the audio feedback and the general space of the room and all of the screaming was awful. The best part though was all of Rob's reactions. He knew he couldn't be heard but the hostess just kept asking questions.
The funniest part though was when Rob did this weird spin ( he does this when his extremely nervous i.e. the Austin film fest footage) and he stumbled to the ground a little. I didn't get a video of it but I've never laughed so hard. Poor guy handled it well I think.
