At the end of the scene where Frank chases the car on a bike, he jumps into the car through the driver's window. You can see broken glass flying, but in the very next shot the driver's window is intact again.
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.
