Gillan had a chaotic childhood which contained sex abuse and drug abuse.
Gillan was working in X-rated movies when she saw an advertisement on a website for actresses to appear as prostitute characters in Game of Thrones, as she recounted: "They were looking for young women with natural breasts and no tattoos, who didn’t mind being filmed naked. So I immediately sent in a picture. They wrote back that they wanted me and I was thrilled because it was an amazing opportunity to do some proper acting. But I had no idea how much it would change my life."
