Ford - who reprised the role of Han Solo for the new J.J. Abrams-directed movie - suffered the serious injury while on set and has revealed the specific series of events that led to it happening.

He shared: "I was just standing in the doorway talking to JJ Abrams, our director.

"The camera hadn't been set up but I was wearing my costume ready to go to work.

"We had a big budget this time. In the original film, the door - if there had been a door - would have been closed with a pulley and a stage hand just closing it. Now we had lots of money and technology and so they built a f***ing great hydraulic door which closed at light speed and somebody said, 'Ooh I wonder what this is?' And the door came down and hit me on my left hip because I was turned to my right.

"And then it flung my left leg up and it dislocated my ankle, and as it drove me down to the floor, my legs slapped on the ramp up to the Millennium Falcon and broke both bones in my left leg."

To this day, Harrison doesn't know who pushed the button.

He told 'The Jonathan Ross Show': "I don't know and I don't want to know."
