An upcoming romantic film shot in Antarctica, recently concluded its shoot in the world's coldest continent. Till the End of the World, adapted from the director Wu Youyin's novel of the same name, centers on the adventure of an arrogant millionaire and a self-contained female scientist. They find love while they are caught in a snow storm for 75 days.

The feature-length movie is set to be released in 2017.

After the 28-day shoot in tough weather conditions, the 40-member crew, including lead actor Mark Chao, returned to China in early December.

Speaking of the experience at a media briefing in Beijing on Monday, Wu says: "One of the biggest challenges was that there was only one chance to shoot each scene in the snow-covered landmass.

"The snowy landscape is easily changed due to human activity. So we had to rehearse the scenes in our minds before the shooting every day."

Producer Cao Xin says that the strong sunlight--95 percent of which is reflected by the ice in Antarctica--was another problem. Seven members, including the Chinese-Canadian star Chao, suffered eye problems on one particular night.

Speaking of the trauma, Chao, 31, says: "My character does not wear protective sunglasses. So one day after prolonged exposure to the sun, I felt my eyes aching and vision blurring. It was scary."

When reports first appeared earlier this year of plans to shoot a fictional feature in Antarctica, it sparked a controversy as some Chinese environmentalists were concerned that the shooting could harm the natural environment.

The crew even carried plastic bags where there was no easy access to toilets.Source: chinadaily.com.cn
