Although this is the 4th film that legendary action icon Sammo Hung and rising martial arts star Jacky Wu Jing have made together, this is the first where they actually share a fight sequence with one another
According to Jacky Wu Jing, during rehearsals of the final fight sequence, Sammo Hung would throw him the occasional friendly 'surprise move' to see how he would react. Of their experiences together, both Wu Jing and Hung have gone on record saying that they have the utmost respect for each other and are very close.
Both Sammo Kam-Bo Hung and Niu Tien agreed that the final scene they share together is their favorite moment of the film.
