'The Karate Kid' starring Ralph Macchio, William Zabka turns 40: The cast then and now

"The Karate Kid" is celebrating its 40th anniversary. The movie launched the careers of many of its young stars, like Ralph Macchio and Elizabeth Shue.

Originally released in 1984, the movie follows the new kid in town, Daniel LaRusso, as he struggles to find his footing and accidentally steps on the toes of the town's biggest bully, Johnny Lawrence. He then finds himself taken under the wing of the older and wiser Mr. Miyagi, who teaches him how to defend himself, and when to use his fists. Lori Bashian is an entertainment production assistant for Fox News Digital. 

In the 40 years since its release, the movie has spawned three sequels, a remake and a television series starring many of the film's original cast. Here is what they have been up to since 1984.
