LIGHTS, camera and too little action.

That about sums up Fann Wong's stint so far in Prague, where she is shooting the latest Jackie Chan gongfu flick, Shanghai Knights.

'The schedule is the most relaxed in my entire career,' says the 31-year-old about her first Hollywood movie in Mandarin. 'It was very relaxing, but that might not be a good thing.'

She even had time to lounge in cafes, reading magazines and watching people go by while she was in the Czech capital.

With only one to four scenes to shoot daily - compared to rushing one episode of a drama serial in a day - she says: 'It's mentally taxing to get into the momentum of the filming.'

She plays Chan's younger sister in Shanghai Knights, which is the sequel to Shanghai Noon. American actor Owen Wilson, who plays the gun-slinging cowboy, returns for the sequel.

After one week on the set, Fann is back for a whirlwind round to promote Bella Skin Care, a chain of beauty centres in Asia.

She will return to Prague on Sunday to continue shooting till July.

Unfazed by the English dialogue she has to deliver, she adds: 'I don't have a lot of lines, and I don't have to deliver them very theatrically.'

It helps that Chan's English is worse.

'Jackie has a speech instructor beside him when we act,' she says. 'I don't know how bad his English used to be.'

The gongfu star, who is known to be protective of his female co-stars, has watched her during a few of her daily training sessions.

However, to her disappointment, she has yet to execute any death-defying stunts.

'Hopefully, I will get to be strung up on wires soon,' she says gleefully, adding that her Chinese dance background has come in handy.

'Of course, I hope this will not be my only Hollywood movie,' says the actress, adding that she has to 'work harder'.
