EXCLUSIVE: Jessica Plummer has joined the cast of John Cameron Mitchell’s How To Talk To Girls At Parties, opposite Ruth Wilson, Nicole Kidman, Elle Fanning and Matt Lucas.

Indie distrib A24 is releasing the picture domestically, which is based on a short story by Neil Gaiman and also stars Alex Sharp — a recent Tony award winner for The Curious Incident Of The Dog In The Night-Time. Gaiman is exec-producing. Producers are Howard Gertler (Mitchell’s Shortbus) and Iain Canning and Emile Sherman (Macbeth).

The story follows a shy teenage punk rocker Enn in 1970s suburban London, and his two closest friends. One night they all sneak into a party where they meet a group of intensely attractive, otherworldly girls; at first they think they’re from a cult, but eventually come to realize the girls are literally from another world—outer space. The leaders of this alien colony have a nefarious plan in mind, but that doesn’t stop Enn from falling madly in love with Zan, one of the colony’s key members. Their burgeoning romance sets in motion a series of increasingly sensational events that will lead to the ultimate showdown of punks versus aliens, and test the bonds of friendship, family, and true love.

Hanway is handling sales. Plummer is an up-and-coming British actress and singer, who was once a member of popular group Neon Jungle. She is repped by the Identity Agency Group in the UK.
