No, he doesn't look like Charlton Heston. Who does? Moses probably didn't.
We owe many things to Moses but perhaps the most important thing is this: He is the only person in the Bible who asks God what is His name. Think about that and then think about God's answer.
"Then Moses said to God, “Indeed, when I come to the children of Israel and say to them, ‘The God of your fathers has sent me to you,’ and they say to me, ‘What is His name?’ what shall I say to them?”
And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you."
