Kinda irritates me that most people only know him for his Willy Wonka film
look at me im so cultured for knowing that he was in more than one film
I don't know why it "irritates" you. This comment is the crap that goes on /r/iamverysmart.
I guarantee that in a week's time, everyone will know every movie he was in. But only now that he's dead will people care enough to watch those movies. That's just the cycle. He was a brilliant man and deserved recognition throughout his career, not just because of one role. Same with a lot of actors who have passed. I'm not trying to say it's people's faults they don't know his other roles, I'm just saying it irritates me that Willy Wonka is the only thing people are talking about, when he did so much more, and so much that was just as amazing.
Just my opinion.
It's not even the only thing people are talking about though. I see people mentioning Young Frankenstein more.
That aside, people are mentioning those movies because they're his most recognizable and that's how most people heard of him in the first place. So of course people are going to put his name alongside the movies that raked people in. It's not reducing his talent, it's "Hey, this is the guy in these films that you loved".
If you care about him so much you should be glad that people are going to be learning more about him now, as well as people who are going to be newly appreciating him, instead of acting like you're on a high horse because you know more than one or two of his roles.
