Why are almost all the explosion scenes in Soviet movies in 1970s and 1980s shot by real blasting, and few special effects are used? At the same time, Japan used special photography methods.

Obviously, because the system and the resources that can be mobilized are different.

1. As a socialist country, the Soviet Union is dominated by the state, and human and material resources can be mobilized free of charge. In addition, the land is vast and sparsely populated, so there is no need to consider safety and damage when blasting.

2. Japanese films are commercial films, and private shooting must consider the cost. If a bomb is used for blasting, on the one hand, this weapon of destruction is extremely difficult to obtain, and on the other hand, Japanese state-owned and private land will also protest because of security issues. With the development of information technology in 1970s and 1980s, using special effects will save a lot of cost and trouble.
