For years, comedian Dayo Wong Chi-wah was strict about the scripts he selected. How things have changed. 'I always thought that as an actor, I shouldn't sell out,' Wong said. 'But then I realised that being serious and strict about roles meant I was limiting myself - I was forcing myself into a dead-end position.' Wong said he has become more relaxed during the past couple of years, taking on roles just for the money. One of those is in House of Mahjong, directed by Marco Mak Chi-sin and co-starring Sam Lee Chan-sum and Cheung Tat-ming, which opened on Thursday. 'To be honest, in the beginning, I just accepted the offer to make money,' he said. 'But in the end I spent a few days discussing the script with everyone in the crew, trying to make it a better movie. The outcome is much better than we expected.' Wong also made Herman Yau Lai-to's Lethal Ninja and Lam Wah-cheun's drinking-game comedy Nothing is Impossible last year. He's hoping to make a breakthrough in his acting career by portraying a villain in a new TVB drama series. 'There's lots of action in it,' said the 46-year-old. 'I'd never made this kind of drama before and I wanted to do it while I was still physically capable. 'I'm not going to play a single-sided or comedic bad guy in the drama. People might hate my character, but they'll understand why.' In 2002, Wong co-directed the comedy Fighting to Survive with Abe Kwong Man-wai, in which he played a public housing estate resident who launches a 'one-dollar bodyguard' business in the community. Instead of directing another movie, Wong (right) said he was now preparing a production for the stage.
