Hard Boiled

During the filming of the scene in which Tequila is running down the exploding hallway with the baby in his arms and explosions at his back was shot twice as John Woo wasn't happy with the first take -the explosions were too far behind Yun-Fat Chow. For the second take, he took control of the explosives button, and set it off far closer than Chow was expecting. "He was really running for his life." Chow apparently was professional enough to ask how it looked after the shot was finished, "but then he turns around and says, 'that motherfucker.'"

Throughout the film, characters fire more bullets than their guns would realistically allow without reloading, John Woo actually explained that he does this on purpose because reloading slows down the action scene.

The Chinese censors requested cuts to the scene where Tequila is graphically shooting thugs in the hospital when he is holding the baby.
