Aaron Kwok Fu Sing and Sun Honglei play a prosecutor and a defendant respectively in their new film Silent Witness.
Aaaron admitted that the biggest reason that he took the film was to work with Sun Honglei, reports HK Top Ten.
He said, "When I knew we had a chance to work together, my first reaction was 'great'. I believed we definitely would have chemistry."
He also said that throughout the film, he had to apply pressure on Sun Honglei, thus the 'eye performance' was very important.
Aaron has never used this method before. He said, "It's mutual, it's not a forceful pressure. It has to be accurate."
