Broaden your experience to be more creatively competent

The more you experience and learn by observing for yourself, the more capably you can portray a range of different subject matter for cinema and fiction, and avoid cliched depictions.

Here is a video from discovery.com of a Giant Pacific Octopus and its keeper at an aquarium.

Observing animals can also be a good way to help develop original animal characters for cinema and fiction, as discussed in the post Animal intelligence and character psychology.
