Academy Award winner Eddie Redmayne may be all set for another run for the 2016 Oscars with his upcoming film, the Tom Hooper directed "The Danish Girl." Redmayne transforms into a woman for the portrayal of his character Lili Elbe, the transgender pioneer and artist, the Huffington Post reported.

The trailer lets audiences in on the pivotal moment in Elbe's life, the moment that she dresses as a woman for the first time. Elbe's wife, Gerda Wegener, who was also a painter, asks her husband to model a women's dress for one of her paintings when her original model fails to show up.

"You will not tell anyone about this," Redmayne says as Elbe in the trailer.

The montage of scenes after it piece together Elbe's story, from the first time she wore women's clothes out in public at a party to seeking gender reassignment surgery with support from Wegener.

"I think Lili's thoughts, I dream Lili's dreams, she's always there," Redmayne says as his character.

Based on David Ebershoff's 2000 novel of the same title, which serves as a ficitional account of Elbe's life, the film follows Elbe's journey as a transgender pioneer, according to the Daily Mail. Born in Denmark in 1882 as Einar Mogens Wegener, Elbe lived as a successful artist and painter in 1920s-1930s Paris. She was the first ever person to undergo a succesful gender reassigment surgery to live openly as a woman in 1930s Paris.
