Paltrow and Kidman to Wed

Gwyneth Paltrow will play Nicole Kidman's wife in their latest film, The Danish Girl.

The film follows Danish artists Einar (Kidman) and Greta Wegener (Paltrow), who found success after husband Einar stood in for a female model Greta was set to paint. Later, over the years 1930-1932, Einar underwent a series of operations widely thought to be the world's first surgical gender reassignment operation.

Paltrow signed on to replace Charlize Theron in the role of Greta.

Anand Turker is set to direct the film, which screenwriter Lucinda Coxon is adapting from David Ebershoff's novel of the same name.

Last week, Kidman said she actively sought out "extreme" film choices that explored all aspects of love, sex, and marriage.

"In the end I hope my life will be a mix of extreme love and bold artistic choices. I've never wanted to be safe. I've never chosen safe relationships. And I've never chosen safe films," said Kidman, reports OK! magazine.

There is no official release date for the film.
