Continuity Errors Were Common
Aside from the fact that re-filming is expensive, a lot of TV shows during that time didn’t have full-time continuity directors. A great example of a continuity error can be seen in episode three of the third season. The new mayor is almost attacked by a bear, but he starts climbing a tree. As the bear rushes toward the camera, you can see in the shot its animal trainer releasing the animal.
The Opening Credits Pay Homage To Andy’s Real-life Dad
At the start of the show, we see Andy and Opie walking together. We see Opie throwing some rock and Andy giving him a shake of his head or a nod in acknowledgment. Andy’s real-life father also shook his head the same way. Andy thought the action was the perfect way to pay a subtle tribute to his father and it became a touching moment that he shared with his fictional son as well.
