Get ready to feel reallllly old: "Karate Kid" Ralph Macchio is 50!
Hard to believe, but Ralph celebrates the milestone birthday today -- 28 years after the movie's release.
And he's been a busy boy since his days as young Daniel-san.
After starring in "The Karate Kid" and two of the three sequels, Macchio continued to work in film, did a musical on Broadway, acted on television and most recently appeared on "Dancing with the Stars."
But what have the rest of the film series' stars been up to?
Sadly, Pat Morita (Mr. Miyagi) passed away in 2005 -- but other stars from the film series have gone on to have success on soap operas, appear on shows like "Glee" and "Mad Men" and garner Oscar nominations and wins.
Check out the gallery above to see how the casts of "The Karate Kid," "The Karate Kid Part II," "The Karate Kid Part III" and even "The Next Karate Kid," with a then-unknown Hilary Swank, all aged through the years.
