Kate Winslet
Kate Winslet made her name as a British actress with performances in period dramas, most notably Sense and Sensibility, for which she won a BAFTA Award for the role of Marianne Dashwood. She made her name as a global star when James Cameron cast her in his blockbuster Academy Award-winning epic Titanic, opposite Leonardo DiCaprio. Afterward, she preferred roles in smaller, less commercial films such as Quills and Eternal Sunshine of the Spotless Mind. For her work in The Reader, adapted from the novel of the same name by Bernard Schlink, she won both the Oscar and the BAFTA in the Best Actress category. Other Kate Winslet films include Heavenly Creatures, Holy Smoke!, Hideous Kinky, Revolutionary Road, Little Children, Finding Neverland, and A Little Chaos.
Winslet consulted with the Centers for Disease Control and Prevention when preparing herself to play the role of Mears, and felt that she was able to understand the constant feeling of being under threat, and the extreme stress, that those who work with pandemics are under every day. She also decided that Mears was the conduit between science and the layperson, rather than as strictly "one of the scientists."
Jennifer Ehle
Sodrbergh always had Ehle in mind for the role of Ally Hextall, having known her for some while and admiring her work in the Liam Neeson film Michael Clayton. Before officially casting her, Soderbergh watched the entire series of British wartime drama The Camomile Lawn, in which she had starred as the feisty and bold Calypso, a character Soderbergh felt was very similar to that of Ally Hextall. Ehle is perhaps best known for her portrayal of Elizabeth Bennett in the PBS miniseries of Jane Austen's Pride and Prejudice. Her other films include Wilde, The King's Speech, Zero Dark Thirty, and A Little Chaos.
