Sanaa Lathan has joined the ensemble cast of Steven Soderbergh’s drama “Contagion” for Warner Bros. Pictures.

Production on the pic has begun shooting in Chicago.

“Contagion” centers on a deadly virus that threatens the human population, with groups from around the world working together to contain the epidemic. Lathan will play the spouse of Laurence Fishburne’s character, the doctor who informs his wife of the epidemic, who inadvertently tells a friend and sparks pandemonium.

“Contagion” is written by Scott Burns and produced by Soderbergh, Stacey Sher, Greg Jacobs and Michael Shamberg. Cast includes Matt Damon, Jude Law, Marion Cotillard, Kate Winslet and Gwyneth Paltrow.

Lathan recently completed the HBO pilot “Tilda” opposite Diane Keaton and recently came off the West End production of “Cat on a Hot Tin Roof.” She previously starred in “A Raisin in the Sun.”

She’s repped by WME and managed by John Carrabino.
