Continuity mistake: Nino gets trussed up in silver duct tape. The boy gets bundled over the shoulders of one of the bad guys, and you can see that there is only a small amount of tape around his legs. They go straight inside the meat packing factory and suddenly in the next shot, there is a huge amount of tape around the boy's legs.
Continuity mistake: Nino is hanging from a meat hook and moves along the 'I' beam. There's a close up shot of the rusty roller that supports the meat hook. Just before it falls off, there is another close up shot and it is a different roller.
Continuity mistake: As Rex runs towards the wire netting to save Nino, the boy has his baseball glove on. He puts his hands up to protect his face, and the glove has gone.
