You're recall the 1969 film ended with a bus hanging over a cliff. Trouble was the bus was full of stolen gold and every step the thieves took towards it put them in greater danger of plunging to their deaths.
The movie ends with Caine's character, Charlie Croker, saying one of Caine's most famous on-screen lines, "Hang on lads, I've got a great idea". Before the credits roll.
Nearly 40 years on and Caine has given his version of what might have happened after that.
"I crawl up, switch on the engine and stay there for four hours until all the petrol runs out. Then the bus bounces back up so we (the gang) can all get out, but then the gold goes over."
"There are lots of Corsican Mafia at the bottom watching the whole thing with binoculars. They grab the gold, and then the sequel is us chasing it."
Apparently this ending had been filmed for the original movie but producers decided against using it, choosing the cliff-hanger instead.
Caine's version of events comes as the Royal Society of Chemistry is holding a competition to find the most original and plausible ending to the film.
Almost 1,000 entries have been received.
Winners will be announced in January 2009.
Over the past 40 years The Italian Job has achieved cult status. Not a lot of people know that.
