Gwyneth Paltrow is joining Nicole Kidman in The Danish Girl, reports Variety.
Thomas Alfredson (Let the Right One In) is directing a script by Lucinda Coxon. Gail Mutrux, Anne Harrison and Linda Reisman are producing, along with Kidman and Per Saari.
The film is based on the true story of Danish artists Einar (Kidman) and Greta Wegener (Paltrow). Their marriage took a sharp left turn after Einar stood in for an female model that Greta was set to paint. When their portraits became wildly popular in 1920s Copenhagen, Greta encouraged her husband to adopt the female guise. What began as a harmless game led Einer to a metamorphosis and landmark 1931 operation that shocked the world and threatened their love.
