Borrowing more than a bit of inspiration from the Chandra Levy murder, this political crime thriller has a brash reporter (Russell Crowe) researching the untimely death of a congressman's mistress. What emerges is a corporate cover-up full of insiders, informants and assassins. Ben Affleck, Rachel McAdams, Helen Mirren, Jason Bateman and Jeff Daniels co-star. It's based on a well-regarded BBC series. 127 minutes PG-13.
