Continuity mistake: Colone has a blue pen in his left shirt pocket. The pen is there during the car ride and throughout the chase scene but disappears when he draws his gun. Later on the blue pen is back in his pocket when Colone says "Happy Friday the 13th". (00:22:35 - 00:45:48)
Continuity mistake: Sissy put 2 ketchup bottles and 1 mustard on the counter top. When she turns to listen to Megan she bumps one bottle knocking over both ketchup bottles. As Megan finishes her story she points to the arriving bus full of kids you can see both bottles are back upright and the second ketchup bottle has moved behind the mustard. (00:19:10 - 00:19:45)
Continuity mistake: Hawes' heart is missing from where it should be beside the grave. When Jason heart punched Hawes he dropped the heart as Hawes fell back into the grave. As Jason turns he can be heard stomping on the heart. The heart may be squashed but it should be there and the caretaker should have spotted it. The broken shovel and gas can are also nowhere to be seen. (00:17:58)
Continuity mistake: Jason's suit is a little dirty but not damaged at all. This is a result of this scene being added months after filming had wrapped. (00:31:16)
Continuity mistake: Jason has been shown to be right-handed but in this scene he has the machete in his left hand. The dart pouch is barely visible and the machete holster is not. In the shot of his head the axe wound is missing. This is all because the film has been flipped - it's a mirror image of a previous shot of Jason walking. (00:28:43)
Continuity mistake: The boy in the blue and gray shirt has a white bag in his hands. The next shot the bag disappears. (00:28:28)
Continuity mistake: In the second row the second girl from the right has a pink bag and doll in her lap. The next shot both are gone. (00:27:25)
Continuity mistake: The liquor bottle has a red and gold label. Later the liquor bottle label is white with gold trim. The change occurred because the caretaker's death was filmed months after the shooting had wrapped. (00:27:14 - 00:30:29)
Continuity mistake: The fence post Tommy removed to stab Jason is still in place on the fence. (00:26:44)
Continuity mistake: When Tommy is handcuffed and stood up he has leaves and debris stuck to his shirt but in the next shot of him standing up it's all gone. (00:26:33)
Continuity mistake: Tommy runs by the same graves multiple times. They use shots from different angles to make the chase seem longer. (00:25:57)
Continuity mistake: This is not the same cemetery as the one in the opening scene, this is a real cemetery. The layout is different. There are no hills or staircases. It has different monuments and tombstones which actually have names on them. The quick shot of Jason's grave is just an insert. All the actors also avoid walking over any graves, and they do not take the same care in the opening scene. (00:25:39)
Continuity mistake: As Jason pulls out the machete for the triple decapitation you can see his sleeve pulled up slightly revealing the Dan Bradley's wrist. It's not Jason's rotted skin seen in the opening. (00:24:18)
Continuity mistake: Roy has somehow circled back and is standing beside the same tree he was kneeling beside earlier when he broke the branch. The vines on the front of the tree were removed and the branch he broke is just below the camera but the tree itself and the trees in the background are identical. (00:22:58 - 00:24:04)
Continuity mistake: When Jason holds up the severed arm and machete there is a small gap in the sleeve where you can see CJ Graham's skin and not Jason's rotted skin seen earlier. (00:22:29)
Continuity mistake: The paint ballers are wearing safety googles which have two indirect vents on the top. These removable vents disappear one by one over the next few minutes. Larry is missing the vent over his right eye, then both vents. Then Katie is missing the vent over her left eye, then Stan is now missing the vent over his left eye and Katie is now missing both vents. (00:20:37)
Continuity mistake: The "spearhead" of the pole Jason is holding is in his right hand pointed into the sky. In the next shot where he goes to stab the tire the spearhead is in his left hand pointed down to ground. (00:13:30)
Continuity mistake: When Lizbeth puts the car in reverse and backs up the shot from the exterior shows the car backing up but the next shot from the interior you can see out the window that the car is not moving. The following shot of the exterior you see the car come to a stop just before the edge. (00:12:58)
Continuity mistake: When Hawes runs away he can be seen in the background tripping and falling over. He is getting back up and racing away to the left toward the truck. The fall may not be a mistake but at no point is he shown coming back. A few shots later Hawes appears out of nowhere behind Jason to the right and attacks with the shovel. (00:07:25)
Continuity mistake: When Tommy holds the mask in both hands before he throws it in the coffin, the strap on the right side of the mask is not connected to the other two straps. They are connected minutes later when Jason puts on the mask. (00:05:59)
