During the film, the crew is seen during a ramp ceremony where the remains of a fallen service member are transferred from an aircraft to a transport vehicle.
It reflected a real-world ritual, something that film director Andrew Bernstein said was important to highlight.
“The more real military and CIA personnel we can include, the more authenticity it adds,” he said.
“We really try to honour the service of these people. Being at Mildenhall lets us see the aircraft, the people – it makes everything more believable, bigger, and more exciting.
“We take that very seriously.”
