WHy woudl they need to use six engines?
Are they stupid?
Surely just disassembling one would be enough?
And its nto like they filmed the real engine really operating, it was all hand cranked and faked anyway
Impressive in a corny sort of way - it would have been MUCH mor eimpressive if they had actually filmed a live operating engine at real time - not the "scene by scene" that they did.
