Non-Fiction (2018) is a French film that takes a look at an aging author and editor in Paris who both juggle their crazy personal lives with the publishing industry. Guillaume Canet stars and shows his ass and back sack in a scene where he puts ON his underwear. No, honey, keep them off. Vincent Macaigne is also naked in a very dark scene. It's dark, but we see a sexy man laying there. There's nothing fictional about that!
