State of Play is a 2009 political thriller film directed by Kevin Macdonald. It is based on the 2003 British television serial of the same name. The film tells of journalist Cal McAffrey's (Russell Crowe) probe into the suspicious death of the assistant and mistress of Congressman Stephen Collins (Ben Affleck). The supporting cast includes Rachel McAdams, Helen Mirren, Jason Bateman, Robin Wright, and Jeff Daniels.

Macdonald said that State of Play is influenced by the films of the 1970s. He explores the privatization of American Homeland Security and, to a minor extent, journalistic independence, along with the relationship between politicians and the press. Released in North America on April 17, 2009, by Universal Pictures, the film received generally positive reviews from critics and grossed $88 million worldwide.
