I research how eunuchs (castrated men) are portrayed in literature. I’ve written the following articles to discuss the referenced films.
Women of All Nations (1931)
Murder 2 A Hindi-language Bollywood film (2011)
The Imitation Game A dramatized biography of Alan Turing, an early twentieth-century British mathematician.
Game of Thrones, an HBO television series, began in 2011 and is based on the books by George R. R. Martin. There are two significant eunuch characters.
“Happy!” Season 1, Episode 7, “Destroyer of Worlds” (SyFy, available on Netflix) has the villain do a eunuch reveal. The relevant two-minute scene occurs approximately 34 minutes into the episode. It is described on Geek.com. The episode aired in January 2018.
And also in podcast:
“The Magic Tavern” has a recurring character, Benedict Whisperbrew.
