Aunt Bee's Cruise: Part 1 - S1-E15
Revealing mistake: Aunt Bee is traveling on a cruise ship. The "water" in the background is a painted backdrop which is made all the more obvious by the painted whitecaps.
Emmett's 50th Birthday - S1-E11
Revealing mistake: As Millie Swanson exits Emmett's Fix-It Shop and passes by the window, she casts a shadow on the painted backdrop which depicts other buildings. The mailman then walks into the shop and he, too, casts a shadow on the backdrop.
Andy and Helen Get Married - S1-E1
Revealing mistake: A shot shows the interior of the church where Andy Taylor and Helen Crump will be wed. Shrubs and trees are visible outside the church entrance but they are obviously just a painted backdrop. As people enter the church, they cast shadows on the backdrop.
Revealing mistake: The painted backdrop depicting the street and distant buildings is much too close to the Mayberry City Council office. As people come and go, they cast shadows on the backdrop.
