 The final cut of " Cog " consists of two continuous sixty @-@ second dolly shots taken from a technocrane , stitched together later in post @-@ production . ( The stitching appears during the moment when the muffler rolls across the floor . ) Four days of filming were required to get these two shots , two days for each minute @-@ long section . Filming sessions lasted seven hours and the work was exacting , as some parts needed to be positioned with an accuracy of a sixteenth of an inch . Despite the detailed instructions derived from the testing period , small variations in ambient temperature , humidity and settling dust continually threw off the movement of the parts enough to end the sequence early . It took 90 minutes on the first day just to get the initial transmission bearing to roll correctly into the second . Between testing and filming , 606 takes were needed to capture the final cut . The team commandeered two of Honda 's six hand @-@ assembled Accords — one to roll off the trailer at the end of the advertisement , the other to be stripped for parts . While several sections of the early scripts had to be abandoned due to the total unavailability of certain Accord components , by the time production finished the accumulated spare parts filled two articulated lorries .
