Consider this: A man from the city decides to buy an otter and move to Scotland in order to write a book about marsh arabs. He paints a cabin, then befriends a lady doctor and convinces her to row a boat while he harpoons a shark. While the man gone on a business trip, the otter is bludgeoned to death by a farmer who explains, “I thought it was just an otter.” If this sounds like a great idea for a movie… you’re too late, it’s already been done.
