Yes. Cazale was DAMN good at acting
How's Annie? How's Annie? Hahaha, How's Annie?

I agree, Cazale was a really fine actor. I think what may have hurt him most, regarding lack of nominations, is he worked with and was surrounded by so many heavyweights and (at the time) slightly better known actors. I remember when I was younger, I would always refer to Cazale as "that other guy in (insert movie name here)"
But what a short, compact, major run he had.

Right. He is very celebrated and uniquely regarded. Same thing when PSHoffman died and people said he was underrated. Absolutely not, he was in tons of movies and was very appreciated by the community and critics alike. I think you mean to say he may not be known by as many people because of his understated performances but he is definitely not underrated.

No, he is not.
Look at his filmography.
Check the critical acclaim.
You did not discover Mr. Cazale.
We're aware of his talent.
Perhaps the OP just wants to reach out for some sense of community.

He was great but not amazing. But to hold your own with then legends De Niro, Hackman, Pacino etc does say a lot. I would've loved to see what else he could've done had he not gotten sick and died. He was talented in supporting roles.
Nothing is as it seems so I wouldn't judge by what you think you see.

But he has always played such annoying roles. I'm surprised everyone on here seems to love him so much.

Yup, I agree too. Cazale's performances were consistently excellent.

I agree 100%. He was a brilliant actor. He was taken way too soon. If he had lived he would rank right up there with Pacino, Deniro, and many other great actors of our time.
