A film about the Japanese bombings of Chongqing during World War II is set for release in Chinese theatres on August 17th.

Shooting for "Unbreakable Spirit" began in 2015.

Starring Chinese actors William Chan and Liu Ye, as well as South Korea's Song Seung-heon, the film revolves around how people learned to survive the bombing of Chongqing, which was hit with massive bombing raids by Japanese aircraft during Japan's invasion.

It also shows how Chinese people, both the army and civilians, were united in their resistance against the invasion.

Mel Gibson served as the art director for the film, which has a budget of over 100-million US dollars.

With over 2,300 special effects, the film has been produced to serve as a memorial for the 70th anniversary of the Allied victory in World War II.
