The bad guy was played by Rod Bartholomew a UK based skydiving friend of mine who now teaches skydiving around the World as an AFF instructor through his business Airwaves.
We used a rubber knife in the air and although on every jump I took the knife from Rod in freefall we never dropped it once ! The funniest thing that happened shooting this sequence was when unusually strong gusting winds and a later than planned exit point meant that I was not going to make the drop zone.
The options open to me were:- a). An alligator swamp, or b). A golf course.
