Waterston mentioned, "The cast and crew of the show treated me like I was their mascot, and I'm sure that wasn't just because of my charming personality. It had a lot to do with the character of Charlie."

He recalled, "Everybody was looking so sad already, I couldn't look them in the eye," when filming his character's death.

"I was supposed to come in and freak out and have a heart attack, I couldn't be feeling all warm and nostalgic," he shared.

He mentioned show creator Aaron Sorkin approached him and said, "Have you noticed what's going on?"

Waterston shared, "I said, 'Yes, I can't look at anyone because it's all the wrong feelings.'"

"After I had several heart attacks and died several times, I noticed that everybody who wasn't on camera was wearing a bowtie. That's what he was referring to. I was referring to the fact that everyone was emotional, he was referring to the fact that as a gesture of affection for Charlie they had put on bowties to mark the occasion of his demise," Waterston divulged.

The Newsroom airs its final episode on HBO at 9 p.m. ET Sunday. The episode is called What Kind of Day Has It Been.
