Think about the Leonardo DiCaprios and Scarlett Johanssons in Hollywood today. They're on top of the world. Their movies are all hugely popular. They are great looking and they command millions of dollars for their movies.

Today's A-listers seem to have it all. What could ever go wrong?

Plenty.

They should enjoy the top now, because time marches on and looks are fleeting. More often than not, once a dreamy, popular actor or actress hits a bad patch of movies, their looks start to follow, and then it becomes a downward spiral.

Remember those celebrities of the '80s we all drooled over? Turns out reality hit a lot of them hard, and now we normal people can enjoy the schadenfreude of their crashing returns to Earth.
