Actress Gwyneth Paltrow has been cast as Nicole Kidman’s wife in the new film The Danish Girl, according to Variety. The Iron Man actress will replace fellow Oscar winner Charlize Theron as Greta, in the film adaptation of David Ebershoff’s novel.

Theron recently backed out of the controversial film, loosely based on the life of the first man to undergo a sex change operation. Kidman will play transgender artist Einar Wegener. Wegener underwent groundbreaking surgery to become a woman in 1931 after pretending to be a female model in a series of successful portraits painted by Greta.

Thomas Alfredson is on board to direct the movie, which is expected to premiere sometime next year.
