Final day of filming!!
Everyone was looking forward to the Bunker Scene because a) it was closer to base camp than the radar site so less distance to carry filming equipment! and b) smoke, darkness, fire and sparks are always fun!
The number of crew members allowed inside during filming was limited because the room itself was not that big and too many people would increase the risk of people tripping over wires – not to mention the heat! With the smoke machine running almost constantly, it got very warm.
