Trivia: While trying to locate Frank via gps, the techie is told to "hack into military satellites" to find him. There is a quick shot of a computer screen with code, and then it looks back at their faces. When paused on the code, you see the words "Command BitTorrent", which is a reference to BitTorrent, a program commonly used to download movies illegally off of the internet. Kind of ironic.
