Names draw attention. I agree that it shouldn't be the main selling point like it was for that one Daisy Ridley-voiced game from a few years back, but celebrities get more media attention which means more consumers hear about the product and re-hear about it, which reinforces the liklihood of seeing or playing or listening to something.

Same for directors or companies or musicians or what have you. If you like someone's work, even if it's just their acting ability, voice or otherwise, you're more likely to consume it than something entirely new by parties you've never heard of.
