Director of "The Great Wall" Zhang Yimou has defended his choice to cast American actor Matt Damon as a lead character in his movie following controversial accusations.

The soon to be released film received backlash following the release of the trailer. There were questions as to why a white actor was playing a role some would consider to be more suitable for a Chinese actor. Some of the disapproval included why there always had to be a white saviour in cultural films.

Yimou has addressed the criticism surrounding his forthcoming movie in a statement. He made it clear that Damon was not the hero of the film but one of a group of five persons of which the other four are Chinese.

“In many ways The Great Wall is the opposite of what is being suggested,” Yimu told American publication Entertainment Weekly.

“For the first time, a film deeply rooted in Chinese culture, with one of the largest Chinese casts ever assembled, is being made at tent pole scale for a world audience.

“Our film is not about the construction of the Great Wall. Matt Damon is not playing a role that was originally conceived for a Chinese actor. The arrival of his character in our story is an important plot point. There are five major heroes in our story and he is one of them — the other four are all Chinese.”
