Another Karate Kid

I hear that there is going to be a remake of the Karate Kid movie. 

Oh, boy. What is it with Hollywood film companies and the way they always seem to want to remake classic movies? 

You cannot do Karate Kid without Pat Morita or even Ralph Macchio (although they did try without the latter in 1994). 

Mr Miyagi is one of the iconic characters of 1980's movies.Whoever is being put in the spot to replace him has big shoes to fill.
