The principals of a new film called "Helios" have met with the media in Beijing to help promote the new film.
Co-directors Lok Man Leung and Sunny Luk, along with Hong Kong actors Jacky Cheung and Shawn Yue have taken part in the event.
Jacky Cheung, who hasn't starred in films for a number of years, talks about why he chose this movie as his comeback:
"I was moved by the story of Helios. I think it has the best plots and scenes. It's different from other Hong Kong movies."
"Helios" is film about military elites from China and South Korea who team up to help deal with a nuclear weapons crisis.
The film also stars mainland actor Wang Xueqin, as well as South Korean actors Ji Jin Hee and Choi Siwon.
"Helios," with a price-tag of 200-million yuan to film, is scheduled to hit the theatres on April 30th.
