Jordan Fox at the Opera

Could it be? A porn flick set in a REAL Opera House (Berlin's Komische Oper)? French pornstar Jordan Fox shared this picture on his FB page, but didn't reveal much --other than an intriguing: "for a new movie". Now, many porn flicks were shot and set in historical movie houses --going all the way back to the 70s. But this must be the first in an Opera House. Phantom of the Opera, the XXX version? Details?
