One of many Jackie Chan's movie stunts that solidified his status as a legend
I think it's also easier to list the things he hasn't jumped off of or on to. He's jumped from:
snowmobile to helicopter
helicopter to train
train to truck
truck to building
building to building
building back to truck
truck to car or motorcycle
car/motorcycle to just about everything else
I can't remember how he got on to or off of the hovercraft at the end of Rumble in the Bronx, but hovercraft were involved.
I guess unicycles and pogo sticks were never used, but there are still a bunch of his movies I haven't seen, so there is still the possibility.
I prefer his fight-oriented movies instead of the action stunt movies though.
