What are the motifs in Catching the Big Fish by David Lynch?

Cinema and David Lynch have had a long and productive love affair. As a painter, Lynch had no desire to be involved with cinema; he only wanted to paint. That is until the painter created a stop motion animated painting/film for an annual sculpture and painting exhibition at the Pennsylvania Academy of Fine Art. The film captured Lynch's interest, and soon, everyone wanted a piece of his creations. A film maker was born.
