If you watch Lost In Translation backwards, Bill Murray whispers something in Scarolette Johansen's ears, then some other stuff happens, then you see her in bed in her underwear.

If you watch I Am Legend backwards, Will Smith blows up a lab in his basement, kills his dog and then says hello to his family after they fly home to NYC in a chopper.

If you watch Grey's Anatomy backwards it's about a bunch of melodramatic bitches.

If you watch the first Matrix backwards, you watch a superhero of some-sort fall in love and slowly but surely he gives up everything he knows until he finds himself in a dead end job getting taunted by the people he was once friends with, including the girl.
