Just weeks after she appeared in Freya Ridings' promo for "You Mean the World to Me", which was directed by Maisie's "Game of Thrones" castmate Lena Headey, the actress shows up in South African singer-songwriter Alice Phoebe Lou's "Galaxies" video, filmed at the Zeiss Planetarium in Berlin, Germany by director Anouk Rhode.
In the video, Williams delivers an opening monologue Lou and her band perform.
Maisie says, "There'll be no humans elsewhere; only here, only on this small planet. We are a rare as well as an endangered species. Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you'll not find another."
