Revealing mistake: When Itto puts the cover on the baby carriage it's obvious that the sudden downpour of rain is just a sprinkler placed in front of the camera. Pay attention to the cover, Itto's clothing and the puddle behind the carriage, they remain completely dry/untouched. (00:11:00)
Other mistake: When the wrapped body parts are going for the mistress (the one telling the story), you can see the right arm dragging itself across the floor. However, the arm that grabs her face from above is also a right hand. How did the murdered wife have two right arms?

Continuity mistake: At the beginning of the movie, Bruce Lee enters a restaurant in the Rome airport and, because he can't read the menu nor speak the language, he accidentally orders five bowls of Campbell's Soup. When the waitress first delivers the five bowls, the soups are very different colors than they are in subsequent close-ups. Disappointed but hungry, Bruce plows into the soup. Ten sequential close-up shots show him dipping his spoon into bright red, tomato-based soups; but, by the time the spoon reaches his mouth, the spoon is dripping creamy white soup, every time.
Other mistake: The opening credits misspell the name of production supervisor Peter Sczygiol ('Sceygiol') and firearms technician Gino Vagniluca ('Vigniluca').

Revealing mistake: At one point when the soldiers are walking through the jungle, one of them steps into a trap and is pulled up into the trees to be killed by Indians. However, if you watch this scene carefully, when the soldier (who steps into the trap) walks into frame you can see a wire already attached to his foot leading up into the trees. He doesn't step into a trap. (00:22:26)
Continuity mistake: During the opening credits, Peter Boyle is seen loading luggage into a red Ford convertible with a rear license plate reading 677 EIY.
