Aha... Yes, I can guess which scene that all was for, as there was what could best be described as an orgy to serve as a background to a scene at one point. I don't recall offhand any of those specific acts, but that's not to say that they weren't panned across in the establishing shot or weren't occurring somewhere in the background during the actual scene while, in the foreground, the lead characters were having a fully clothed, uncomfortable conversation and wishing they were somewhere else.

It's entirely possible that on rewatch I could come to the conclusion that there was a lot more sex than I thought... I know that there were a few panning shots of the prostitutes from the local saloon entertaining guests and so on, but I'd still call Game of Thrones the much racier show.

Regardless, I now do wonder what the standard consent form might be for filming a "background orgy". Thankfully my day as an extra on "The Dark Knight Rises" didn't require me to learn.
