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.

In the next shot, the cue ball is on the same side as the 8-ball and the other two balls are now close to the cue ball.
