A tall tale is a story with unbelievable elements, related as if it were true and factual. Some tall tales are exaggerations of actual events, for example fish stories such as, "That fish was so big, why I tell ya', it nearly sank the boat when I pulled it in!" Other tall tales are completely fictional tales set in a familiar setting, such as the European countryside, the American frontier, the Canadian Northwest, the Australian outback, or the beginning of the Industrial Revolution.

Big Fish is a 2003 American fantasy drama film directed by Tim Burton, and based on the 1998 novel Big Fish: A Novel of Mythic Proportions by Daniel Wallace.
