Writing According to producer Michael Deeley the film started "as a modest concept for a TV drama concerning a robbery set in and around a traffic jam in London's hectic Oxford Street thoroughfare", that was originally conceived by
Ian Kennedy Martin. Ian's brother
Troy would eventually buy the idea from him "with the vision of creating a feature film set in Italy." The script was optioned by Oakhurst Productions, the company of Deeley and Stanley Baker.
Ending According to a "Making Of" documentary, producer Deeley was unsatisfied with the four written endings and conceived the current ending as a literal
cliffhanger appropriate to an action film which left an opportunity for a
sequel. The documentary describes how
helicopters would save the bus seen on the cliff at the end of the first film. 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." In Deeley's own memoirs, he stated that a sequel would have had an opening involving helicopters lifting the bus up to separate the men and the gold that then sees it taken by the Mafia, who proceed to push the bus off into the ravine. 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 element number 79.
Locations in Turin (pictured in 1961) where the three Minis are pursued by a police car before they go back down it and escape The opening scenes with the Lamborghini Miura were shot at
Great St Bernard Pass, and have been recreated by the owner of the car. The interior of the prison that held Bridger was
Kilmainham Gaol in
Dublin, Ireland. The exterior, seen when Croker leaves, is
HM Prison Wormwood Scrubs in west London. Upon his release, Croker stays at the
Royal Lancaster Hotel in Bayswater, London, where he celebrates with what is implied to be an orgy; his room became a favourite haunt of rock stars after the release of the film. Denbigh Close,
Notting Hill, London W11, was used as the location for Croker's home. The training sessions shown for the Mini drivers were at the
Crystal Palace race track in
Upper Norwood, south London. The attempt to blow off the doors of the bullion van, which caused its total destruction and produced Croker's line "You're only supposed to blow the bloody doors off!", took place at Crystal Palace Sports Centre. The
Crystal Palace transmitter can be seen in the background. The meeting at the misty funeral was filmed in
Cruagh Cemetery, in the foothills of the Dublin Mountains. The
office block that doubled as the Turin traffic control centre was Apex House in
Hanworth,
Middlesex, the then head office of the television rental chain Thorn (
DER). The second car, tumbled down the chasm by the Mafia bulldozer, was another Miura that had previously been in a serious accident and was not roadworthy. Lamborghini confirmed in May 2019 that the
Italian Job Miura (the roadworthy one) had chassis number 3586. The Minis featured in the climactic chase were 1275cc
Austin Mini Cooper S models. Production took place just as the manufacturer, the
British Motor Corporation, was preparing for the introduction of the
Mk2 Mini, which was launched just before the film's public release. The Minis used were 1967 Mk1 models, fitted with future-dated 1969
G-suffix number plates to match the year of the film's intended release, despite that any 1969-registered Mini would be a Mk2, not a Mk1. BMC provided six new Minis (two of each colour) to the production at cost price. A further 25 were bought on the secondhand market via BMC's agent in Switzerland. Ten of these secondhand cars were Cooper S models and the remainder were standard 848cc models which were modified to various degrees to match the genuine 'star cars' as required for filming. All 16 Mini Coopers were destroyed or rendered unroadworthy in the course of filming, along with nine of the replica cars, leaving six 848cc replicas surviving intact. These were abandoned in the film crew's storage unit in Turin when filming concluded and their subsequent history is unknown. Gold cost $38.69 per
troy ounce in 1968, so four million dollars in gold bars would have weighed about , requiring each of the three Minis to carry about in addition to the driver and passenger. Since a 1968 Mini only weighs , each of these vehicles would have had to carry times its own weight in gold. The original
Aston Martin DB4 belongs today to a private English collection. According to several sources, the "Aston" pushed off the cliff was a
Vignale Lancia Flaminia mocked up as an Aston. The two
Jaguar E-Types that suffer from the Mafia's revenge were restored to original condition. A
Land Rover Series IIa Estate, registration BKO 686C, is used to get to the convoy before attacking and is modified with window bars and a
towbar. A
Ford Thames 400E is used for the football fans' decorated van; this has been referred to as the
Dormobile, the name of a common
camper-van conversion
coachbuilder. The cross-Channel ferry featured in one scene is the . The ship spent many years as a day cruise ship in Greek waters before being scrapped in 2013. The "Chinese" plane delivering the gold to Turin is a rare
Douglas C-74 Globemaster, of which only 14 were built and only four passed into private ownership. It had been abandoned in Milan by its owners and was moved to Turin for filming. It was destroyed by fire in 1970. The black
Fiat Dino coupé of Mafia boss Altabani was bought by Peter Collinson but became so rusty that only its doors remain. The bus used to transport the three Mini Coopers is a
Bedford VAL with
Harrington Legionnaire bodywork, registration ALR 453B, new in April 1964 and specially converted for the film. ==Music==
