Denzel Washington attends the Nobel Peace Prize Concert press conference at the Plaza Hotel on December 11, 2010 in Oslo, Norway.

*Denzel Washington and Ryan Reynolds are nestled into Universal Pictures’ “Safe House,” with country star Tim McGraw knocking on the door. The singer is in negotiations to join the action thriller written by a former Us Weekly editor.

The story line follows the only surviving agent of an attack on a CIA safe house (Reynolds) as he tries to get a lethal prisoner (Washington) to a second safe house before being taken out by violent forces that want them both dead.

McGraw would play a CIA agent who is the mentor to Reynolds’ character. He may not be all he appears to be.

“Safe House” was written by David Guggenheim, an Us Weekly editor who worked nights on the story and whose spec script landed him a new career. Daniel Espinosa is directing.
