Elle Fanning is attached to star in How to Talk to Girls at Parties, an adaptation of Neil Gaiman's 2006 short story which was nominated for a Hugo Award.

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.

Elle Fanning most recently starred in Maleficent alongside Angelina Jolie, and she also voices a role in Laika's stop-motion feature The Boxtrolls. 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.
