* HarsherInHindsight; Bigelow is killed with a poison that glows in the dark. In 2006, Alexander Litvinenko was murdered by having (non-glowy) radioactive material injected into him. (''Series/LawAndOrderCriminalIntent'' combined both the film and the real-life events for their episode "30".)
* LeaveThePlotThreadsHanging: The film never does explain how [[spoiler:Halliday]] got involved in the original iridium theft/sale that instigated the film.
** He didn't. He was simply trying to frame [[spoiler:Eugene]].
* {{Tearjerker}}: The entire film [[spoiler: especially when it's revealed Bigelow really was just one tenuous loose end - he was killed because he inadvertently and innocently notarized a bill of sale for stolen iridium.]]
