Mistakes
There is a scene where Keanu Reeves slides down the bridge on his back. In the next scene where he meets Rachel Weisz in train station the camera shows his back. There is nothing wrong with his jacket, it looks like brand new. How's that possible? See more...
Chain Reaction mistakes
Factual error: In a radio news voice-over shortly before the first chase scene, the newsreader comments that "Calls have flooded in from all over the world regarding Dr Barkley's research." He then goes on to mention that the Royal Academy in England has expressed an interest. The "Royal Academy" is more formally the Royal Academy of Arts. They probably mean the Royal Society, which is the most important scientific institution in the UK.
