I think Hollywood believes men are shorter than women in real life because all the tall model type females move to La-La-Land.
It’s one of the oddities of humanity. Short men suffering from Napoleon complexes seek fame; and tall women who already stick out from the crowd often figure they might as well make money at it. And then set builders and camera men get to have a lot of fun making 5’2” men look taller than 6’ women.
