Secrets of the Dead (2000) : 23x5

There are only two accepted representations of William Shakespeare that are considered "official"—but could a portrait that has been hanging over a family's mantelpiece for the last 50 years be the third? British window washer Steven Wadlow, whose father bought the portrait in the 1960s, is on the hunt to prove the painting is indeed genuine. If so, it could be worth as much as $200 million.
