Whatever Happened to Tony O’Dell From ‘Head of the Class’ and ‘Karate Kid’?

Then: Tony O'Dell played Alan Pinkard, the argyle sweater-wearing, Ronald Reagan-loving preppy -- yup, that character was pretty much an '80s-sitcom staple -- on 'Head of the Class.' O'Dell was a very successful child actor, and he also played Cobra Kai member Jimmy in 'The Karate Kid' and the 'The Karate Kid, Part II.'

Now: O'Dell is putting his experiences as a child actor to use as the acting coach for the Disney show 'Shake it Up,' a role he also had for the movie 'Diary of a Wimpy Kid.' The 51-year-old stays active on social media and embraces his legacy as a Cobra Kai on his Twitter bio.
