So as opposed to a fake Kai Tak courtesy of Noble House, Shaws decided to go for a more authentic location for the finale of The Taxi Driver and use the actual terminal building of the airport. Now, although I went in and out of HK via Kai Tak on a few occasions (once I even missed my boarding call and still managed to get through customs and run down the terminal strip to my gate in time for the plane to leave - it's very disconcerting having a member of the airport staff approach you as you run and refer to you by your name and telling you to run quicker!!).
Anyway, moving on to my *spoiler alert* and our intrepid taxi driver accompanied by the HK Police head to Kai Tak to catch the mastermind of the bank robbery as he boards his flight to some exotic distant locale (probably Vancouver, right? :)).
When cornered he threatens to blow every up but his suitcase contains nothing but all his money from the robbery and it soon ends up all over the floor.
