Continuity mistake: In the scene at the gas station, Frank Martin grabs Valentina's arm to remind her of the bracelet and to not go too far. When he does, one shot shows him grabbing below the bracelet, the next shot shows him holding her above the bracelet, then the next shot below it again.
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.
