After his parents are killed in front of him, because they crossed between parked cars in order to escape the crush of people leaving the theatre, billionaire (no, really, well ok no not really) body actor Dave "Dave" Prowse spends his days when not having his voice dubbed over by a distinguished sounding American acting Great, attempting to rid the world of the menace of parked cars.
At first he honed his body to be up to the task of confronting the parked car threat but then he wondered, "how will I strike fear into the hearts of those bastard stationary vehicles?" only it sort of sounded more like "'ow wul OI stroike feur inta thu 'earts ov dose barrstarrrd stayshunaaarrry ve'culs".
Long he pondered until a freak confluence of events involving an ambulance and Dave's red-green colour blindness inspired him, it didn't mean much but to his hard cider addled mind the green cross would be the perfect symbol of his quest.
And so while the world must think that Dave "Dave" Prowse is just the bloke inside the Vader suit, he is in fact Green Cross Man!.
And don't you dare cross near parked cars, or he'll get very pissed off or something.

I liked that film when I was small.
