Okay, not exactly. But Nicole Kidman and Charlize Theron will play a married couple in an upcoming film, The Danish Girl, based on the true story of Danish artists Einar and Greta Wegener.
In the 1920s, Greta (Theron) was a rising artist in Denmark. Apparently, one day, her husband, Einar (Kidman) stood in for a female model Greta was supposed to paint. Greta enjoyed painting her husband's portrait so much that she created a series of paintings based on this mysterious model -- who was actually her husband posing as a woman. They became very popular in Copenahgen, and Greta became a sensation.
Over time, Einar began to transition to living as a woman full time. Ultimately, she had the first male-to-female gender reassignment surgery, in 1931. The operation shocked the world and threatened their status as a married couple.
The Danish Girl is based on the David Ebershoff novel of the same name, a fictionalized account of the Wegeners' true story.
Kidman will be producing the film. Anand Tucker (Shopgirl) is attached to direct.
