Goofs

When Rama's face is cut by a machete when hiding within an apartment's wall, it leaves a deep, ragged and swollen wound. However, when he exits the apartment his wound is suddenly much neater and more superficial.

During the execution scene, when the all the rounds in the revolver are supposed to be spent it is placed on the shoulder of the final victim. At this point it's possible to see into two of the chambers, where the tips of unspent ammunition are visible.

But since only two men had been shot, the implication is that the munition is bad, which also explains why for the last one a hammer is used.

Punch sounds are heard when no punches were laid. This is in the American version of the movie. In the original all sounds are fine. The goof is created by bad dubbing/ sound editing making the movie understandable for that country.
