When The Lady is in the helicopter, her hands are tied. Then when she falls her arms are stretched out behind her. When she meets up with Hooten in the river her hands are tied again.
Hooten places his bundled blanket in his hammock. After a cut it's back in his hand.
The helicopter used by Pascal has a registration of ZS-RTG. The "ZS" is the IACE code for South Africa, showing the helicopter sequences are shot in South Africa, not South America.
The final shot showing Hooten walking down a street in a city somewhere in Brazil shows traffic moving on the left side of the road. Traffic in Brazil and in most of the South American continent moves on the right side of the road, showing that, as with the helicopter sequences, the scene was shot in South Africa, not South America.
