Karen Mok Man-wai's mind-bending new film hitting Hong Kong cinemas

Karen Mok Man-wai has been on the move lately. The singer-actress has been running around so much these days she has to take a long pause before answering one of the easiest questions you may encounter in a media interview: Where are you based?

"I'm based … on the plane," she says, finally, letting out a hearty laugh. "Actually, I'm not very sure where I'd call home nowadays. My office set-up is in Hong Kong, but all the work is in greater China - and mostly on the mainland. I live with my mum whenever I'm in Hong Kong, although my time in this city is really limited - maybe only several days a month. Hong Kong is more like a place of transit for me. My real home is probably London because that's where my husband is."

It is on one of those precious days in Hong Kong that we sit down with Mok, who turned 44 last month, though she doesn't look her age. For months the elegant songstress has been traversing the mainland with The Age of Moknificence concert tour, which marks her 20th anniversary in the entertainment business. "This touring experience has been great," she says.

"It's different from the past when I mainly played in stadiums. Because it was a jazz album that I last released, we chose to play concert halls this time to evoke the more intimate atmosphere. The audiences are almost close enough to touch me. It's a whole new experience for them and for myself - and that's why they think the tickets are worth the price even though they're really expensive."

Mok's music career is not the only reason that she's been spending the majority of her year on the mainland. Her new film The Great Hypnotist, which is set to open in Hong Kong cinemas on July 17, was released there in late April.
