Gotta agree with breezy about the guitar thing. What I've never understood is why the actors involved never even bothered to learn a single chord fingering in order to at least give a semblance to actual playing of the instrument. It appears this was an issue to Johnny Cash as well. When the film of his life was being cast he insisted that whoever played his part should "at least know how to hold a guitar properly."

I recall an interview with an actress many decades ago in which she revealed that she pretended to be ironing clothes with both hands in order to give the impression that she was playing the piano in a film. Of course, the camera was posed so that her hands were never actually seen.

But I digress...

The entire premise for this thread impresses me greatly. And here I thought I was anal! You folks put me to shame.
