 Director David Dobkin had a difficult time choosing a suitable Asian  actress who could do movement work, emote well and speak decent  English. He then saw clips of Wong, Fann (qv)s videos  _"Wo lai ye" (2001)_ (qv) and _"Qing she yu bai she" (2001)_ (qv)  and requested to audition her in London, which she did attend. She  subsequently got the role and her number of scenes were increased by  30%.
