Brad Pitt made a surprise appearance at the first screening of World War Z Saturday in London, ahead of the film’s highly anticipated premiere Sunday.
"This has been a long-time coming – this film. I think we've got something original," Pitt said, thanking the media who flew in from around the world. "I think we've got something genre-bending. I think we've got something terribly realistic for summer fair. I'll let you guys decide."
World War Z, based on the novel by Max Brooks, stars Pitt as a United Nations employee who must find a way to stop the pandemic that's defeating armies and collapsing governments. The film hits theaters June 21.
