That fella was wired for sound, I think. Perhaps just excitement and high spirits. Poor Sable discovered that early in the evening, when he wandered through the room and stopped to introduce himself. He didn't say 'who' he was - just his first name (not that we would have recognized his last name . . .)
So, he says (this is all paraphrased) 'are you excited about the film?' and Sable says 'well, I've already seen it, but yes' and he says (in slightly hysterical tones), 'WHAT? How? I haven't seen it!' and she says, 'I got the DVD from the UK' and he says 'don't you recognize me, then?' and she says, 'well, no, but I didn't pay that much attention to the extras' . . .
and then he about came unhinged! It was funny. 'I wasn't an EXTRA,' he huffed - and puffed - and looked terribly put-upon.
I think he was totally digging that neither Sean nor Chris were there, so he could play the part of 'hunky movie star' (such as it was).
She deflated that bubble for a bit, for sure!
