I think the idea is that it's a pop-up menu that would display over top of the film as it plays when you hit the menu button. So it's a placeholder of sorts, but if you hit the menu button during that scene, that's how it would appear.

I like and appreciate a Blu-ray popup menu as much as the next guy, and would like to see it included, but I think a menu that comes up before the movie starts would fit what I think Harmy is aiming for better (and I think is what is actually being discussed anyway). If someone wants to nostalgically view Star Wars in the original Klingon, it would be a bit of a disservice to force them to fumble through options in a popup menu as the opening text is already flying by and the Blockade Runner and Star Destroyer are on their way.
