As an absolute bookworm since a very young age, I see the charactors in my mind from the description in the book given by the author. My first time seeing Little Women by Louisa M Alcott on screen, was a horrible shock. The characters did not look like my imagining of them and I disagreed passionately with the looks of the one who played JO (the character I cared about most) . What upset me most was for a time when I thought of them , the tv characters took the place of my imagining. However I soon got my own people back and reading the book again to check, was positive that the tv had got it wrong!! So it taught me the lesson that I still use. I read the original book, and make up my own mind as to how characters look or behave . It is that direct contact from author to reader. That is the best, but it is fine for people to experiment and try out different things if they wish. Now it is good that disabled actors play disabled parts, and not having able bodied taking these parts. Mind you I still think the very best plays for both characters and scenery are on the radio!! I wish they would put more good plays on the radio. Many a winters horrible day spent the afternoon ironing or baking with the radio to keep me company. TV is brilliant to show wild life and gardens etc but if there is a choice of one it will be the radio for me.
