Liddell was one of Scotland's most celebrated athletes.

Born in China in 1902, he was sent to Britain at age 5 to be educated. He won a gold medal in the 400-meter sprint at the 1924 Paris Olympics.

Liddell returned to China in 1925 and worked as a teacher in Tianjin for nearly 20 years.

In 1943, he was held in Weihsien with about 2,000 other Westerners. He died in the camp at the age of 43 of a brain tumor.

The film's ceremony in Weifang was attended by two of Liddell's daughters, as well as several former detainees who knew Liddell from their time in Weihsien.

Hakon Daniel Torjesen, 89, says the film clip shown at the ceremony touched his heart.

"Although the years in Weihsien were a time of scarcity, they were also a source of strength. Each of us shall remember the Weihsien experience," Torjesen says.

Shin spent six years writing the script, a process that involved him visiting many of the places where events in the film take place.
