Continuity mistake: When the Kung Fu team is training, the coach throws an egg onto "Steel Leg's" foot. It breaks and some of the yolk gets on the ground. But when the fat player starts eating it, the whole yolk's on the shoe. (00:33:30)
Visible crew/equipment: When Hung has his cigar lit, you can see the camera and a man's face reflected in Hung's sunglasses. The man is wearing a white shirt. (01:02:00)
Continuity mistake: When Sing is about to clean the floor, he drops his jacket and then he drops his shirt on the jacket. When it cuts, the shirt has moved away from the jacket. (00:49:40)
Continuity mistake: When Sing is shooting at Team Evil's goal you see the keeper fetching the ball in the goal's upper corner. When it cuts you see the keeper hanging from the goal holding the ball, but he has moved further away from the corner. (01:03:55)
Revealing mistake: After Steelleg's and Iron Head's song, Steelleg is taken outside for a fight with some thugs. He kicks a ball into the stomach of a guy, making him fly backwards and roll over several times before he slides away on the ground. Look at his neck in the shot from behind - you can see the construction he was dragged by under the shirt.
Revealing mistake: When we see one of the Team Evil players get his drug we see his veins grow. Watch the veins in his face as he is moving his head. The veins aren't moving, it's as if the veins are stuck to the screen or something. (01:05:00)
Other mistake: In the very last scene, we see a poster for Time magazine telling the story of the husband and wife Kung fu athletes. The bottom line reads "Wins World champion Bowling again". It should be "Championship".
Continuity mistake: When Sing is about to fight the gang you see him from behind and the gang stands scattered around him a few feet away from a pole. When it cuts they have totally changed position and are now standing close to each other and close to the pole. (00:19:40)
Continuity mistake: When Sing is talking to his second brother you see a scattered pile of hair stretched over the second brother's forehead. In the next shot the pile of hair is more gathered on the forehead. (00:29:05)
Continuity mistake: Right after the Team Evil keeper has saved one of Sing's shots, you can see him bend the upper pole on the goal, but later on the pole is fine. (01:04:00)
Continuity mistake: When the Shaolin Team is playing their training match, the rival team chooses to do their "final attack" to the goalkeeper, throwing one of their shoes to him, but he manages to put all of the shoes together making a rapid movement. If you look closely while he's making this movement, you'll see that he catches more than a dozen shoes, and there are even more shoes on the ground, although the rival team has only seven players and each player throws just one shoe.
Continuity mistake: When Sing is drinking his milk you see the bottle is full. In the next shot the bottle is less than half full. (00:21:55)
Revealing mistake: When the Kung Fu team is playing against a football team (before the team that has two women), one of their players is running with the ball stuck to his stomach. He knocks two players down by running into them, and the goalkeeper jumps on him, holding him by his clothes, but he is dragged after the player. You can see him float above the ground for a moment (while holding the player's clothes), just before the goal is made.
Revealing mistake: When the six brothers are reunited at the rooftop of the building, we see the fat boy walking with a scarf around his neck that is waving in the wind. If you look closely, you will see the string that makes this effect possible.
Continuity mistake: When Sing is talking with the fat brother who eats chips and the brother is walking away you see his cheeks are clean. Two shots later his face is covered with chips. (00:27:55)
Continuity mistake: When all the people are dancing in the street you can see Mui dancing a bit on the side. In one shot her hands are covered in flour. In the next shot her hands are clean, and then they are covered in flour again. (00:14:40)
Continuity mistake: When the Kung Fu team is playing their first match (the team that beats them up), all the Kung Fu players are getting their powers back. There are clips of each one of them with an explosion behind them. Look at the goalkeeper - in the clip with the explosion, his hair is all messed up, but when he jumps into the goal, his hair is combed. (00:43:10)
Continuity mistake: At the beginning, Sing gives Fung his "business card", but Fung refuses it and without rolling it up puts it into a can which is kicked away by Sing afterwards. Later, Fung finds the can and the piece of paper is rolled up inside.
Continuity mistake: When the brother, who catches the ball with his stomach, has taken over as keeper, you can see him standing with the ball attached to his stomach. The part of his stomach above the ball is covered with clothing. When it cuts you can see his bare stomach where the clothing should be. (01:11:50)
Continuity mistake: When the Shaolin Team is being introduced to their rival team for the test match, the manager of that team accidentally drops a hammer with a wooden handle. When he picks it up, you can see that the hammer now has a metallic handle.
