There is an iconic film from the late 1980s called Field of Dreams that has stuck in my memory. It dates back to the time when Kevin Costner was a huge Hollywood star. In the film, Costner plays an Iowa corn farmer who starts hearing ‘voices’, which he believes are telling him to convert one of his fields into a baseball diamond. Costner follows the wishes of the voices and slowly out of the corn stalks surrounding the diamond appear the figures of baseball stars from the past. I forget how the film ended. But I can remember leaving my first viewing with a smile on my face.
