From 47:00 - 48:00 the showrunners of Industry talk about Kit showing his ass. They say Kit is very proud of his ass(they repeat this statement quite a few times). They also make it out to seem that the ass scene is Kit absolving himself for using a butt double in GoT but if I am correct, Kit ended up showing his ass twice more in later seasons.
- From the discussion it also seems this will be Kit's only nude scene this season so take it for all it's worth, who knows when or if we'll ever see him nude again
