No, it isn't. I don't know who it is. I was actually taking an architectural shot with the Mamiya C330S (some years ago) and just as I was about to shoot he glided into frame, stopped and looked back for his girlfriend some yards behind. "Looks like Brian Cox", I thought, so took a shot. He then moved on, and didn't seem to notice me at all.
Nice architecture. St Leonard's Church, Stockbridge, Edinburgh. I didn't record the film.
