After much anticipation, TVB recently revealed all the three important characters in the 2017 drama "The Exorcist's Meter" will return for the upcoming sequel. As reported on Mingpao, actress Mandy Wong will be joining Kenneth Ma in the new drama, reprising her role as the doctor Cheung Chi Yuk - now with supernatural powers that enables her to help Ma Gwai in his work. Hubert Wu, who previously played the spirit Shek Gam Dong, will be playing Mok Wai Ho, Kenneth's childhood friend who died when he was younger. On the other hand, Moon Lau, whose character died in the previous instalment, will reprise her role in the sequel, but as a spirit who silently guards Kenneth's character. Asked if Ma Gwai and Cheung Chi Yuk will finally have a happily ever after this time around, Kenneth shared that there should be a happy ending this time - though added he will be paired with Zoie Tam. credits: cinema/sg.yahoo
