In his acceptance speech, Skarsgard thanked “the ladies of the show… for making this boy feel like one of the girls”.

And he added: “Speaking of incredible women, I want to thank my mother, who flew out all the way from Stockholm… to be here tonight. That means a lot to me. Oh. And thanks for giving birth to me. That was pretty cool as well.”

Big Little Lies won several gongs, including outstanding limited series, a leading actress trophy for Kidman and supporting actress award for Laura Dern, at the 69th Primetime Emmy Awards.
