How was this film made?

These stunts are basically done by post-production from the materials taken in the early stage.

1, a gripping and thrilling fighting scene, first of all, the director's request, the creation of martial arts fingers, and the performance of actors. Some shooting actions are not fast, so we can speed up the action by compressing the time in post-production, and with the rapid switching of shots, we can create a fierce effect. Thrilling scenes, such as flying around, were completed by hanging wires, and then the wires were removed. There are also thrilling actions on the cliff. For example, actors can do it in the studio, shoot on a blue background or a green background, and then shoot on location. Later, when added up, people were put on the cliff. Hehe, the examples I gave are all popular expressions, which are convenient for you to understand.

2, big cars, planes and the like, that is also a small problem. Some films cost a lot of money, and those who use airplanes are usually rented and filmed by themselves. Of course, the real plane won't explode, it's post-processed, and most of it is fake.

3. Crushed cars, houses, overturned trains and plane explosions are basically taken with models. Make a realistic model first, and create a more realistic effect through the combination of post-production and real shooting. To put it bluntly, it is all hidden.

Now the development of science and technology, especially the development of computers, has laid a solid foundation for film production. Anything visual can be made by a computer. I'm afraid you can't think of it, as long as you can. Of course, this requires professional technical strength. Few movie special effects productions in the world are top-notch, so it depends on the money invested in movies.
