"Interestingly that some of the characters did not turn out the way Jim and Allen had envisioned them"

This quote by Mary Tyler Moore talks to the creative procedure of composing and how it can be unpredictable. It suggests that when Jim and Allen were writing their story, they had a particular idea of how the characters would end up, but when the story was completed, the characters had actually taken on a life of their own and had actually become something different than what was originally pictured. This speaks with the power of creativity and how it can handle a life of its own, often leading to unexpected and fascinating outcomes. It likewise talks to the importance of being open to the imaginative process and allowing it to take its own course, as it can frequently cause something better than what was originally planned.
