Collateral prequel to Heat? "SPOILER" Heat intro & Collateral Ending

Rating: 10/10 (10 December 2006)

Hey everyone i just have a theory that Collateral is a prequel to Heat in the sense that Heat's intro starts off showing a Train or skytrain. The first minute or so and Collaterals ending the last shot is tom cruise in the skytrain as it is leaving the shot in same fashion of Heats intro the train is coming into shot. anyways what do u guys think? i think its a neat idea and collateral was happening right before or as robert deniro steals that ambulance. anyways check it out guys i think Michael Mann did this on purpose cuz both movies are set in LA and it would be something like the movie Crash, how each story is interconnected. so reply back if u think the same?
