The people who do casting for movies clearly understand it.
I think “it” here is different from the thing you’re claiming.
What I think it’s clear they understand: many people do in practice deduce a lot about someone’s personality from their face.
What I think you’re claiming: such deductions can be made with some reasonable degree of accuracy. (I assume you also claim: this holds even if you exclude people with medically legible characteristics like Down syndrome or fetal alcohol syndrome.)
(It’s plausible-but-unclear-to-me that your claim is true, and separately plausible-but-unclear-to-me that the people who make movies understand it.)

Well, something along the lines of “deducing personality from shape of the skull and other facial characteristics” used to be official science.
