The Beastie Boys, Mike D and Adam Horovitz, turned down a request to use their 1994 song "Sabotage" in promos for the film. In his will, Adam Yauch prohibited the use of his music in advertisements.
In the scene where Breacher is typing in statistics at his desk, the pictures of his family above his computer are actual pictures of Arnold Schwarzenegger's family. Pictures of Patrick Schwarzenegger are visible.
