Titanic
In the 1980 film Raise the Titanic, directed by Jerry Lameson, salvagers raise the shipwreck from the bottom of the ocean to the surface.  However, this is impossible to do in reality.  The Titanic broke in two, and the wreck is partially stuck in the bottom, buried under more than a yard (1 m) of mud in some spots.  The ship has been on the ocean floor for more than 100 years, and would shatter into many more pieces if disturbed.  Worms and other animals have eaten away much of the wood and many other parts.
