Cherrie Ying Choi-yi hopes her latest role won't leave her career in a hangover. The 23-year-old Taiwan-born actress rose, and occasionally had to stagger, to the challenge of playing a teacher who resorts to the seedy world of late-night drinking games. 'It was really hard to film the drinking-game scenes,' says Ying (right), who also stars in Jackie Chan's action comedy Rob-B-Hood. 'Unlike the mahjong and card-game scenes, where we can set up everything before rolling the camera, we had to remember every sequence of the drinking game and we needed to do it all over again for different shots.' Ying's character in Lam Wah-chuen's Nothing is Impossible (which opens next Thursday) gets involved with the pub pastime after she's dumped by her boyfriend who takes up with a professional drinking-game competitor. The part also required much improvisation, and although scenes were filmed after pubs were supposed to have closed, late-night revellers often stayed behind, wanting a piece of the action. 'You never know what a drunken person will do,' says Ying, who acted out the scenes in sobriety with co-stars comedian Dayo Wong Tze-wah and young action actor Andy On Chi-kit. 'Dayo came up with loads of ideas on set and we filmed several different versions for those scenes.' And it's unlikely Ying will become a regular at drinking-game haunts in Hong Kong or Taiwan. 'The entire room gets filled with a stinky odour. Even if I didn't drink a drop of liquor, I would smell of alcohol when I went home.' Ying is also making her mainland television drama debut soon and says although she's willing to consider most movie roles, she'll be more than happy to take on sober characters. 'There aren't many movie roles around nowadays. Many actors are waiting to get a role. I'm already very happy that I still have movies to make and many of them are big-budget films.' Ying made her movie debut in the Johnnie To Kei-fung and Wai Ka-fai hitman saga Fulltime Killer in 2001 before starring in a series of comedies including Fat Choi Spirit (2002), Mighty Baby (2002) and To's Throw Down (2004).
