Will Sandin was born in 1969 so really young Michael was 9?

Just been thinking about this and wanted to make sure I wasnt missing something. Saw he was born on April 8th 1969. If Halloween was filmed in May of 78 he would be 9. Why was he made to be 6 in the movie? Just because a killer 6 year old is scarier than a 9 year old?

He’s just a fictional character, it doesn’t matter how old the actor is, hell the actress playing Danny in Terminator is a teenage girl, but the actress is 32

Yea, I figured that. Just seems like with the amount its pushed him being 6 years old and him always signing his autographs as Michael age 6 I thought he actually was.

This. Nancy Loomis was 28 during filming of Halloween, and she was playing a 17 high school girl
