Brad Pitt and Angelina Jolie have stepped out together at the premiere of zombie thriller "World War Z" -- Jolie's first public appearance since announcing last month that she had undergone a double mastectomy.
The couple walked a black, rather than red, carpet at the world premiere Sunday of the big-budget film, which stars Pitt as a United Nations employee
battling to save the world.
The pair wore complementary black outfits as they signed autographs for fans in Leicester Square.
Jolie revealed last month that she had had her breasts removed after discovering she has an inherited genetic mutation that puts her at high risk of breast and ovarian cancer.
Jolie's mother Marcheline Bertrand died from ovarian cancer at 56, and the actress' aunt died of breast cancer last month.
