It's not based on a true story. The plot and characters of 'The Great Gilly Hopkins' were crafted by the writer for literary purposes rather than being drawn from real events or people.
I'm not sure specifically which role Billy Porter played in 'American Horror Story' without looking it up. There are many seasons and various characters in the series.
I'm not entirely sure specifically as the term is rather broad. It could refer to the works of Gilly Macmillan within the genre of fantastic fiction. Maybe it's about the unique stories, characters, and themes she creates in this fictional realm.
Overall, 'What She Knew' is a gripping tale that explores themes of family, trust, and the lengths one will go to protect their loved ones. The plot is full of twists and turns that keep you guessing until the end.
I recommend the light novel Pokémon Breeder to you. The protagonist of the story was running a Pokémon breeding house and living with a group of cute Pokémon. In the story, Gilly Egg was the name of one of the Pokémon, and it appeared very frequently! I hope you like this fairy's recommendation. Muah ~😗
Billy Elliot is based on a true story to a certain extent. It incorporates real elements but may have fictionalized parts to enhance the drama and entertainment value.
