Poole sued Darrel for unlawfully using Poole'sidea for an animal robot as a character in Darrel's science fiction movie. Darrel admitted that he had received a model of an animal robot from Poole, but he denied that it had any substantial similarity to the movie character. After the model had been returned to Poole, Poole destroyed it. In order for Poole to testify to the appearance of the model, Poole 
must show that he did not destroy the model in bad faith. must give advance notice of his intent to introduce the oral testimony. must introduce a photograph of the model if one exists. need do none of the above, because the "best evidence rule" applies only to writings, recordings, and photographs.
