In the script, Martin is black. I went with a more hispanic look, based on his last name and the fact we alreayda had two balck supporting characters in the book. The younger Martin is trying to play it cool, where the older Martin seems to have found himself more. And as a fireman, he just HAD to have a moustache! In the younger version he might be trying to grow one, but hasn’t been able to. In the book, I gave the young Martin that iconic Rolling Stones t-shirt because he’s always raving about that band.
