Ballistic: Ecks vs. Sever (2002)

This is a story of two spies, who are lifelong adversaries, engaged in a cat-and-mouse hunt. Jonathan Ecks (Banderas) is an FBI agent hunting the other, Sever (Liu) a rogue NSA agent. What they learn, however, while trying to kill each other... is that they might be on the same side, and faced with a threat greater to each other than themselves.
