Colbert, like all of us, wanted details about Marnie's awkwardly awesome sex scenes. “The sex scenes breed a kind of intimacy,” Williams said, but admitted that she and her scene partners would giggle about it to get through it. Pulling back the curtain on how they shoot nude scenes, she told Colbert that she was “basically a never-nude” because she was always wearing something, even if it was a stick-on contraption that often ended up covering more of her scene partner than of her. When Colbert asked about watching Girls with her parents, Williams says that after all they've seen everyone is finished feeling scandalized. We will have to take her word for that one.
