Let's Talk About Ceps
Pretty much every actor who worked on the orig TP said it was the best thing they ever did. I'd imagine they were only too happy to do it. On the cusp of kicking the bucket or not.
There were only a few who actively refused to do it iirc. One was Harry Truman
The actress who played Margaret "Log Lady" Lanterman was really dying of cancer during filming and I think didn't survive to see the premier go on air. Her last phone call with Hawk had me genuinely in tears.
The Norma Jennings actress died not long ago too. She was always one of my favourite characters - so kind and wise and beautiful but also so incredibly sad. Seeing her finally get together with Ed was one of the emotional high points of the otherwise mostly very bleak Return.
