How did they managed to time the incoming train to be able to jump out exactly at the right moment out of the tunnel??? Isn't it like unnecessary putting your life in danger when it stops being about survival and becomes a JACKASS???
i saw this and it reminded me of watching magic shows and trying to figure out how the tricks were done.
train scene: one shot is of a slower than normal train approach in tunnel; at one point you can see them actually keep up and put distance from the train. I say them because you will also see a total of 5 guys. Bear; two guys on either side; camera guy and someone next to camera guy.
another shot is of Bear - all by himself leaping out of the opening of the tunnel. no other person besides him or around him. So I think they were in cohoots with the train; after filming the shot above. And with everyone out of the tunnel Bear stood at the edge of the tunnel entrance with the camera guy in front of him. Signaled the train to come; waited for it - then they both ran/jumped out of harms way.
that climbing of the chain over the railway bridge. i suspect he was harnessed under his jumpsuit with a safety line because the camera lighting had switched to a brighter mode during his climb; so that the line would get washed out.
Of course everyone involved had to have signed an NDA to prevent leaking these tricks to the public.
