Continuity mistake: When JB dreams about singing "Master Exploder" in the small bar, he points at one guy in the audience and literally blows his mind. When he starts pointing you can not only see JB's face, but also how his elbow is in a slight angle. In the next shot the camera shows the guy JB is pointing at and his elbow is completely stretched. The views change several times and the angle of his elbow changes after every cut, until the guy's brain is finally blown out.

Continuity mistake: When the water wheel begins to roll, with Norrington and Will atop and then snatches up Jack, its blades (buckets on the outside rim) and two sides of the axle face a specific direction as it gains speed.

Then later on the beach, as Elizabeth watches, just as the wheel rolls and falls over in the close-up, the wheel is actually rolling in the opposite direction - just note its blades. Also note the bizarre change of its axle's wide and narrow sides. (01:52:40 - 01:56:50)
