Winning an Academy Award is supposed to signify the ultimate dream when you work in Hollywood. There are dozens of precursor awards that take place between December and February of every year, but there is something special about the Oscars. It's not just the glitz and glamor - it's the fact that you're officially a part of history. While we often get cynical and complain about the Oscars on a yearly basis, no one can blame an actor for getting excited about winning. It could potentially mark the moment that ultimately signals the highlight of their entire career. Of course, there are no guarantees in life and winning an Oscar does not mean you are guaranteed to find work for the rest of your career. Hollywood is not obligated to call you first for every movie role that's available thereafter, and there have been many actresses who have found this out the hard way. They've gone from being A-list actresses to yesterday's news within just a couple of years, with people wondering what happened. For those of us on the outside, it does not seem to make much sense. But, as this list proves, it's just the brutal nature of show business. This is a list of 10 actresses whose careers went downhill after they won Hollywood's biggest prize. Many of them still work today, but for some reason, they keep appearing in only bad movies. Is it their own fault for making these choices, were they always less talented than we thought, or has Hollywood condemned them to a life of mediocrity for seemingly no reason at all?
