FWIW I like the BTS footage too. But I don't know if it is popular with many other customers. Or whether all performers are happy to go along with it.
GG seemed to shoot more BTS when first he was exploring possibilities in his new studio, but now we just seem to get the scene footage from the main set.
I got the feeling many of the female performers didn't like it. Especially being followed all the way into the showers. When they don't want to go along it gets to feeling a bit creepy.
It's been a while since the last BTS from Giorgio... Sure it's not a requirement, but it's always nice to have some girl feedback, extra sequences or anything aside the scene itself.
