I was born 1984, and while i’m very well aware of who he is i don’t think i’ve ever seen a single movie of his. Though that might be more due to random chance than anything else. I watched whatever was on TV growing up so i’ve seen quite a random selection of fairly old movies, his were just never among them.
Anyone born after the 90’s i can imagine that the odds of them knowing who he is is probably much lower.
