Upon being discharged from the hospital, Randy receives a note from the promoter. In the note, the word "your" is used incorrectly in the sentence "Your a warrior". The correct usage would have been the contraction for "you are" which is "you're".
Randy is seen jumping up from his bed using both arms, after receiving a coronary artery bypass. If he really had his sternum bone cut he couldn't, or shouldn't lift anything with his arms over 5lbs for as long as it takes for his sternum bone to heal properly.
The promoter mentions that Ram's match with Tommy Rotten will be for "the strap", which refers to a promotion's title belt. However, following Ram's victory over Rotten, he is not seen holding a title belt or announced as the new champion.
Before one of Randy's matches, Randy is putting tape on his arms. One shot there is tape on one arm then the next shot there is no tape on the same arm, then there is tape on it. This is for the left arm.
Randy is shown a couple times getting his roots bleached. Once at the salon and another time when he tries to do it himself at home. Both times after his hair is bleached, his hair looks exactly the same, with dark roots.
As the "Ram" is preparing for his first match of the movie, he is seen taping himself up. He is bare chested, but when the mo-hawked wrestler enters the room, the "Ram" suddenly has a blue flannel shirt appear on his back.
When Randy wakes up in the hospital he is not on a ventilator machine and is breathing on his own (he is wearing a nasal cannula with oxygen); Yet as the camera pans out in the next scene it can clearly be seen that he has been intubated and is attached to a ventilator machine that is breathing for him.
Pam is a topless dancer at a bar in NJ that serves alcohol. However, in NJ, if a bar serves alcohol, the dancers must be clothed in at least a G-String and pasties and it's called a "Go-Go Bar". If a bar does not serve alcohol, the dancers can be nude.
When Randy is in the pharmacy he is paged with the message "Robin Ramsinski, your prescription is ready in the pharmacy". Stating that Randy had a prescription (or any other specific material items) waiting for him is a violation of HIPAA (the Health Insurance Portability and Accountability Act). The pharmacy is allowed to say his name and call for him to come to their front desk, but that's it.
When the neighbor boy is telling Randy about Call of Duty 4: Modern Warfare, he says that it is set in Iraq. While Iraq is not specified as a location in the game, one of the four Call Of Duty 4 locations IS an unnamed country in the Middle East (the other three locales are Azerbaijan, Russia, and Prypiat, Ukraine) and given world events at the time the movie was made, the kid's assumption is plausible.
