Miracle Man - S1-E18
Continuity mistake: In the establishing shot of the courthouse the subtitle reads "Kenwood County Courthouse" but you can read on the building that it is the "DeKalb County Courthouse". (00:15:15)
Continuity mistake: In the scene where Merle is the in big box late 80's chevy with big 20-22 inch rims he is shown driving it in the barn yard drinking, playing music, and zombies following him. The shot changes a few times within the same scene with the big rims on, in one shot the car is shown with him driving it but the stock rims (15") are on the car, the paint of the car looks a little darker too. Then the shot changes again while he is still driving it and the big rims are on the chevy again. The shot that shows the stock rims is a pretty fast shot so it could be easy to miss.
