That's pretty cool, what did you do on the set?
In Episode 6, there was a scene with Elle and Claire in an airplane - in reality it was a huge airliner cabin mounted on a hydraulic platform called a gimble - I did some rigging work (lighting, mainly) and some finishing touches on the walls, around the windows, etc. It was cool but there were over 50 people doing the same thing so it was easy to get lost in the crowd.
Check it. The one and only pic I was able to shoot before being told to "Put that shit away" by NBC security.

The other scene I worked on was in Ep. 7, when Meridith finds out her brother Flint has been captured and talks with him through the holding cell glass. I just held a boom mike for that scene inside the cell, it was the end of the day and people wanted to go home. Also in the scope of the show the talent was pretty B-List for that scene so all I had to do was volunteer and they let me do sound.
Eric Roberts (The guy who plays Thompson, the boss at Primatech) borrowed my cell phone during that scene and called some area code I didn't recognize. I'm glad I get free long distance!
Does your contract prevent you from asking for autographs??
Eh, not really, but the talent really does not appreciate fanboyism on set - Hayden (who demands to be called "Hadey P" by people her age) is kind of a cool chick, I argued with her about saying sup AND giving the sup nod at the same time... Masi Oki has a new iPhone which he let me play with, and Krystin Bell is kind of a bitch!!! But yeah!
So... no, I could have asked, chose not to. Non-Disclosure Contract only forbade me to reveal plot details before the episodes aired.
T'was a religious experience to say the least.
