<P> In interviews in 2003 and 2008, Michael Caine revealed that the ending would have had Croker "crawl up, switch on the engine and stay there for four hours until all the petrol runs out...The van bounces back up so we can all get out, but then the gold goes over ." The bus containing the gold would crash at the bottom of the hill where the Mafia would pick it up . The sequel would then have Croker and his men trying to get it back . </P> <P> In 2008, the Royal Society of Chemistry held a competition for a solution that had a basis in science, was to take not more than 30 minutes and did not use a helicopter . The idea was to promote greater understanding of science, and to highlight the 100th anniversary of the periodic table, on which gold is one of the 118 elements . The winning entry, by John Godwin of Surrey, was: Break and remove two large side windows just aft of the pivot point and let the glass fall outside to lose its weight; break two windows over the two front axles, keeping the broken glass on board to keep its weight for balance; let a man out on a rope through the front broken windows (not to rest his weight on the ground) who deflates all the bus's front tyres, to reduce the bus's rocking movement about its pivot point; drain the fuel tank, which is aft of the pivot point, which changes the balance enough to let a man get out and gather heavy rocks to load the front of the bus . Unload the bus . Wait until a suitable vehicle passes on the road, hijack it, and carry the gold away in it . MIT physicist Mike Follows claims to have come up with a more practical ending . </P> <P> The opening sequence of the film featuring Beckermann driving his Lamborghini Miura through The Alps was filmed on the Great St Bernard Pass, Aosta, Italy, with the opening scene featuring the Dardanelli Viaduct, which was constructed in 1961 . The large house featured momentarily during the sequence is the Maison de Refuge . </P> <P> The tunnel in which Beckermann abruptly meets his demise at the hands of the Mafia was shot at La Thuile on road SS26, Italy . </P>
