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.
Deliberate mistake: The hero breaks through a window from a balcony into an apartment. The way it breaks into small pieces indicates that it is safety glass, not regular window glass, obviously for the safety of the actor.
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.
