Andy Lau Tak Wa, Ray Lui Leung Wai, Hu Jun and Gordon Lam Ka Tung attended.
Wa Jai in the film plays an invincible character, and director Alan Yuen Kam Lun said that Wa Ji on and off screen represented the invincible spirit of Hong Kong people.
Child star Jacqueline Chan Pui Yin also attended. In the film she played Wa Jai's god daughter. In her first promotion with her god father, she praised him as handsome and a super hero.
On her first day a car ran over Wa Jai in the scene. After watching it she said it was impossible because Wa Jai could not die; Wa Jai joked that since then she became "the invincible siu keung (cockroach)."
Asked if he got along better with child stars after becoming a father, he said that he did not need to become a crook to play a crook well.
