Singing stars Twins are eager to take on film roles which require them to cry. Manager Mani Fok Man-hei revealed that 22-year-old Charlene Choi Tsoek-jin had recently turned down a role in an action movie because she wanted to play characters who showed more emotion. The other half of the duo, Gillian Chung Yan-tung, said she wanted to shoot an ill-fated love story. 'I like the genre, and the settings are often beautiful. It's also challenging,' Chung, 24, said. The popular duo recently completed their first Putonghua album and are at work on their next release.
