Revealing mistake: When Michelle is binding Topper's hands to the bed you can see the cloth hiding her breasts. (00:30:30)
Revealing mistake: When Walters is electrocuted, the kettle on his head is not resting on it but is fixed on the grid behind him, as to prevent it from falling off. Since Walters moves his head slightly, so should the kettle.
Continuity mistake: In the beginning when Topper is about to fight, he puts a red bandana around his head. As he is walking to the fight, one of the flaps of the bandana is draped over his shoulder. The shot changes when he gets to the fight, and both flaps are now behind his shoulders.
Continuity mistake: When Harbinger jumps out the plane he has face paint on but when he lands it's gone.
Visible crew/equipment: When Michelle is at the dinner she asks Topper for a light and strikes it on her leg. As she starts to move her leg, you can see the black strip on her leg to light the match. (00:27:30)
Revealing mistake: When Walters strikes down his guard with the fly-swatter, he slumps against the wall, but actually never comes in contact with the 'Halarm' switch.
Suggested correction: As he slumps against the wall, the alarm button is between him and the wall. And as he slumps down, his body is against the wall and button causing the alarm to go off.
Revealing mistake: The cloud which drenches Topper at the railroad station casts no shadow over him.
Continuity mistake: Just before the fight in Thailand, Topper arms his wristguards with M&M's and sprinkles which he shows to the crowd and his opponent. A few minutes into the fight, he backhands the referee, who somehow gets gummi bears on his face. (00:12:00)
Continuity mistake: When the American prisoner is being tied to the electric device, the twisty-tie is on his bare skin. In later shots, it is on his sleeve. (00:22:20)
Revealing mistake: When Topper is fighting the Thai Fighter, they break the ladder that sends some people falling down. Before the shot cuts, you can see the guy with the pink shirt falling, and he has a dummy attached to him. This is not the same as other dummies who are obviously meant to be noticed (like the guy holding the "John 3:17" sign).
Other mistake: When Michelle removes her mole to give it to Topper, it pops off and is visible for a split second in front of the pinky knuckle of the hand she removed it with. They continue on as if she successfully removed it and gave it to him. (00:50:06)
Continuity mistake: When Topper is trying to get the keys to free the colonel, he knocks the pepper-shaker over, but there's no visible concentration of pepper. After the colonel gets the keys, a mouse is shown on the table. It goes up to the newspaper and sneezes from the mound of pepper which was not there before. (01:12:40)
