In particular, all the action scenes in the cramped airframe were taken on by the actors themselves, without using stunt actors.
In the film, Ma Ran Do and Thanh Son transform into two brave bodyguards, trying to protect passengers from the organized attack plot of the group of pilots played by Thai Hoa, Vo Dien Gia Huy, Bao Dinh and Ray Nguyen. The actors shared that performing a close-range scene right on the narrow path of the plane was a huge challenge, just needing one wrong move was having to start over. Thai Hoa said: In a small space, we had to do long scenes, many camera angles at the same time. everything must be coordinated absolutely accurately".


Thanh Son revealed that during filming, the collision was inevitable, even he had caused his co-star Ray Nguyen to "eat" a rather painful shot. Vo Dien Gia Huy also admitted to having scratches many times due to colliding with a hard object, but it is inevitable to bring realistic footage.
To achieve high efficiency, the director asked the actors to practice carefully with the cascadeur, then directly performed the entire filming scene. It was the dedication and best efforts of the cast that created a tense, dramatic atmosphere, truly recreating a thrilling confrontation between the crew and the group of pilots in the air.
With careful investment and sacrifice by the actors, The War in the Air promises to become a new mark in the Vietnamese action film genre when released in theaters on September 19, 2025.
