Revealing mistake: When Yulaw and Gabe are having a confrontation next to the MRI machine, Gabe jumps across the table and kicks Yulaw. Here you can see the attempt at face replacement on the stunt double as Gabe, which looks fake and plasticy. (00:34:50)
Revealing mistake: While still fighting on the cat walk, Yulaw does a spin kick at Gabe's face. You see Gabe react as if he got kicked in the face, and tumbles over the side. You can see the kick never even contacts Gabe's face as the stunt double reacts to it. (01:07:45)
Revealing mistake: During the fight between Yulaw and Gabe, while on the catwalk up high, they both jump into the air. Yulaw kicks Gabe, who falls to the ground quickly. The shot showing Gabe hit, was poorly done, showing him fall much too slowly, and having a soft impact with almost no bounce at all. (01:07:55)
Chosen answer: After he says he will go to the hospital, his wife says "ni shuo de" which simply means "you said so" (so now he has to do it).
