Not Believable
Once the first season finished, Elinor Donahue made the choice not to return. Why? Personally she felt that she had absolutely no on-screen chemistry with Andy Griffith. Later on Griffith said that their lazy relationship was his own fault, as he had a hard time showing affection on-screen. This translated on-screen of course as their relationship didn’t appear believable. However in contrast, Griffith had no issues showing affection toward Aneta Corsaut.

Now Andy Griffith admitted that the show’s original premise was supposed to follow the story-line that set up from his appearance on Make Room for Daddy. Therefore the idea was that because Mayberry was so small, Andy Taylor wasn’t just the Sheriff, but also the Justice of the Peace, the editor of the local newspaper, and the Mayor. However, when they sat down to write the series, Andy thought the premise was far too ridiculous, so he asked for Andy Taylor’s duties be only be as the Sheriff and the Justice of the Peace.
