I came >this close< to getting a photo of my Son in his Agent Coulson costume with Tom Hiddleston on the Marvel stage today, but it didn't happen.
We got there about an hour in advance, asked if it was possible, and the Marvel people (who are always AMAZING) made it happen. With hoards of people waiting to see TH, they parted the crowd, brought us right up front and we got to sit at the bottom of the stage, about 10' from where he entered, and where he signed autographs for an hour.
Then they grabbed us and told us to get at the end of the line. We were probably 5-6 people from getting to him, and he was abruptly whisked off by his Publicist (from what we were told) in order to get to his next appointment.
Damn, so close.
