15Ralph Macchio - Fizzled Out
Not every career in Hollywood is built to last. However, at least some actors are fortunate enough to have an impact. A good example of this is Ralph Macchio. Macchio has not been in anything noteworthy in decades. Nevertheless, as a young kid, he did manage to star in one
of the most popular movies ever: The Karate Kid, a beloved 1980s classic.
He got his start in another 80s classic The Outsiders. He also starred in The Karate Kid's two sequels, as well as the early 90s comedy hit, My Cousin Vinny. After that, he presumably appeared in other things, but it would be a great challenge to find anybody that has any idea what those things are (other than being in a cast of all B-list has-beens on Dancing with the Stars).
