As reported by Variety, Purnell will be taking on a currently unspecified lead role in the upcoming series. However, sources close to the show have revealed Purnell’s character will be “upbeat and uncannily direct with an all-American can-do spirit. “But an intensity in her eyes says she might just be a tiny bit dangerous.” Along with her aforementioned work, Purnell has also had roles in Miss Peregrine’s Home for Peculiar Children, Disney’s Maleficent and Kick-Ass 2. Purnell’s casting follows the announcement that Tomb Raider and The Hateful Eight’s Walton Goggins will also be starring in Fallout. As with Purnell, no official details about Goggins’ character have yet been revealed, although there is speculation he will be playing a Ghoul - one of the Fallout series’ many mutated humans, whose condition is a result of prolonged exposure to radiation amid the Great War. Westworld series creators Lisa Joy and Jonah Nolan will oversee the project, while Bethesda’s Todd Howard and James Altman will take on executive producer roles. Filming is expecting to start later this year, with more cast announcements likely to come before that.
