Movies being named after animals is not unusal in the cine industry, even if the said movie isn't about the particular animal or about an animal at all. The Pink Panther for example is a franchise of comedy-mystery movies with a genius detective at the center, whereas the Shia LaBeouf starrer Eagle Eye is an out and out action thriller.

Tamil films are no exceptions to this line of naming and Kollywood has a long list of movies that are titled after animals, stand-alone and hyphenated.

When MovieCrow recently reported that Yaanai [Elephant] might be the proposed title for director Hari's upcoming movie with Arun Vijay [later confirmed by makers], conversations around the topic panned out thus.
