If you look closer at the pic,
1. There are no rear doors.
2. The floatation pods are too low to be a Westland fit.
3. You can see that the Scrapheap a/c was fitted with 2 engines.
4. The main giveaway as to what it isn't, is that there are no leather seats.
Where was it filmed?
Perhaps it is a prototype Czech Scasp PZH3.
