Agyness Deyn will play the heroine in a film adaptation of Sunset Song, a 1930s novel about a woman running a family farm in the face of growing economic pressure.

Deyn's role as Chris Guthrie, the movie's female protagonist, is her first lead in a major motion picture. Terence Davies will direct the film and Peter Mullan has been cast as Deyn's costar. Filming will start later this year.

"When I read the script I fell completely in love with the character and the story," Deyn said. "I can't wait to get started and just hope that I can do Chris Guthrie justice!"

Deyn has starred in a number of short films and played Aphrodite in the 2010 movie Clash of the Titans. This Spring she landed a role in a British production of The Leisure Society. Take a look at all her roles — onscreen and off — in the gallery.

>> The first full week of Spring brought plenty of inspiring new-season styles — and even a few surprises.

Brooklyn Decker traded in her usual low-key ensembles for a plethora of out-of-this-world designer looks: Giambattista Valli, Isabel Marant, and Stella McCartney each made appearances at photocalls for the actress's new film, Battleship. Models Miranda Kerr, Lara Stone, Candice Swanepoel, Karolina Kurkova, Agyness Deyn, Jessica White, and a newly-brunette Jessica Stam were also all spotted out and about — and though each looked just as chic as ever, it was their two very pregnant colleagues, Molly Sims and Lily Aldridge, who really stole the show.

There were also plenty of standout casual styles spotted on the streets — Elizabeth Olsen and Emma Roberts each looked effortless in transitional coat-and-trouser ensembles, and Kate Moss and Jessica Alba each sported rose-hued jeans.

However, perhaps it was Elletra Wiedemann who most aptly captured the week's prevailing mood, when at an event hosted by Vogue and Tod's. She exclaimed, "I really just wanted to dress up!"

See who made the list— and what everyone wore — right here in our best-of-the-week slideshow.
