The short story is set in 1970s London, following two teenage boys who attend a party. While one boy has no trouble mingling with the female guests, the other shy boy comes to learn that the girls aren't exactly human. The feature adaptation, written by John Cameron Mitchell (Hedwig and the Angry Inch) and Philippa Goslett (Little Ashes) focuses on a punk kid versed in music and the arts, and a female alien tourist (Elle Fanning), who wants to break free from her tour group to explore the most dangerous place in the galaxy, the London suburb of Croydon.
John Cameron Mitchell is directing and producing alongside Neil Gaiman and Howard Gertler (How to Survive a Plague, World's Greatest Dad), with Fortissimo Films' Michael J. Werner and Winnie Lau serving as executive producers. No production schedule was given.

John Cameron Mitchell most recently directed the 2010 drama Rabbit Hole starring Nicole Kidman and Aaron Eckhart. Neil Gaiman has a number of projects in development, including Sandman at Warner Bros., The Graveyard Book at Disney and the Starz series American Gods.
