Revealing mistake: The hero breaks through a window from a balcony into an apartment. The way it shatters and crumbles into such small pieces indicates that it is breakaway glass, not regular window glass, obviously for the safety of the actor during the stunt. (00:55:25)
Other mistake: The last surviving gangster is walked out of the apartment building with the police at the end of movie. He is covered with blood on his hands, face, and clothes, but his white tennis shoes are immaculately clean.
Factual error: Throughout the film's high-energy choreographed fight sequences, Rama is repeatedly struck in the arms, legs and back with machetes. He not only suffers no wounds, but his tactical gear isn't even lacerated.
Suggested correction: Depending on what part of town his gear, the angle and strength of the blow, and how sharp the machete is, there may have only been negligible cuts. Apparently loose fitting clothes can sometimes be enough to keep a blade from cutting some of the time.
Rama's gear doesn't show even minimal lacerations or abrasions after multiple attacks.
