Actually the idea is a common one in literature and movies. One I remember, "Tales of Manhattan", follows an expensive tail coat from the first owner and how it changes the lives of the different people who own the coat till it finally ends up on a scarecrow out in a field at the end. I can think of a lot ways this idea could be done with a pool cue.I like the idea. I think it would work best if the movie started with a scene with the current owner of the cue and worked it's way back to the cue maker or forest, just to put an interesting spin on the plot.
It is also best to make the story about the people who have owned the cue and not about the cue itself. The cue is just the common thread tying each of it's interesting owners stories together. I would also suggest to use a fictitious cue maker and or brand name of the cue so you don't artificially raise the value of any specific line of cues, unless McDermott, Lucasi or Meucci etc....were going to fund the movie.
