When the truck that David and Holly are hiding in is stopped by the sheriff, it has a plain white driver's door. When it stops a short while later to let them out, it has a "Produce" sticker on the door.
The shirt David is wearing before his first transformation in the jail cell is not the same shirt seen during that metamorphosis. In this episode and others, Hulk-out/Hulk-in scenes from previous episodes are used; disruption of wardrobe continuity being the result.
After the Hulk transforms back to David during the cliff scene, Holly has on the handcuff.When she appears by the truck with the negatives, the handcuff has disappeared without explanation.
It is bright daylight when the cops bring David to the police station. Not much time passes before he escapes, and it is now nighttime.
During the car chase the speedometer shows them travelling at 80 mph. The scene changes to David shifting gears where the speedometer arrow is fully to the left showing 0 mph.
During the car chase Holly's position changes from shoulder to shoulder with David in close-ups and apart in the long shots.
When the Hulk is holding the girl's hand as she is hanging off the cliff, we can clearly see the safety harness connected to the Hulk's left foot and the safety line running down to the stunt woman.
