Continuity mistake: When Max is phoning the Chief to let him know the mission's been accomplished, he takes the oars out of the oarlocks before opening his shoephone.

Continuity mistake: When the owner of the shop is vaporized, at first his hands are both in front of him. The shot changes and now one arm is instantly thrown back behind him.
Continuity mistake: When Max is attacking the boat there is a shot from inside the cabin. Watch the door. Before Max shoots, there are a series of holes in the shade covering the door (they look like bullet holes). Max begins firing and there is another shot from inside and bullet holes begin appearing in the walls. The holes in the shade however, are gone.
School Days - S1-E3
Continuity mistake: When Max is walking around the school grounds he walks up to man breaking a piece of wood. The man breaks a piece of wood and then bends down to pick up a new piece, leaving one on the ground. The shot changes and Max is standing there talking and the man breaks the piece of wood and bends down to pick up another one (which should be the last piece). However there is another piece left on the ground.

Continuity mistake: During the joust scene, several tyre marks on the ground from the motorcycles disappear from the ground.
Continuity mistake: When Max brings the coffee to the doctor's office, his suit is dark blue. After the opening credits he has no time to change, so how come his suit becomes dark gray?
