On my bluray - 0:37:30 to 0:37:35. He moves from the center of the screen to the right, and has a glass of champagne in his right hand. He nods to someone just as he walks out of the shot. Beard and moustache, bald spot on the back of his head (sorry EH). String quartet is in the foreground of the scene.
All accurate. No offense taken.
I do believe it is. (The one holding the glass, not the one in the dress.)
That’s him.
Dopers Assemble!
Hah, I got some screengrabs last night but hadn’t posted them yet.
haw haw, beat you to it!! 
Am I the only one who thinks Elendil’s Heir looks a bit like Ra’s al Ghul?
Good gracious. Is that Mitt Romney in the background? (I like your companion’s dress, BTW.)
Not anymore!
That’s me, but I’m not Ra’s al Ghul.
Although I suppose that’s what you’d expect me to say, isn’t it?
Saw it! Very cool, Elendil!
And speaking as a friend, you’re just as handsome in real life!
My blushes, BMalion…
Hello, Elendil’s Heir, I came across the news that Marvel Studios is going back to Cleveland to shoot some scenes for
Captain America: The Winter Soldier.
Any chance you will be making another cameo? 
Unlikely. That really was a once-in-a-lifetime experience; just wouldn’t mean the same to do it again. I also doubt my luck would hold and that I’d either (a) be chosen as an extra or (b) have any screen time.
YouTube now has the scene. See in the middle of the screen at the 0:26 mark:
Good deal! I am so envious. I’m in Indianapolis and wanted to get over there to try and be an extra, but lacked transport. The next time I see it, I’ll look for you!
Bumped to post a new link, since most of those above are now dead.
I see you! You’re right at the very beginning of the video clip!
Yup. Hard to believe it’ll be a decade next month!
