Filmsack has a segment I enjoy, wherein the host Scott Johnson describes what he imagines different actors' breaths smell like. It's always hard to get it out of your head after you hear it.
1. Renee Russo. Every time I see her in a movie she looks like she's been sick and blowing her nose for 4 days. She was perfectly cast in Outbreak.
2. Old Peter O'Toole. The dude acted until he was like 300 years old. I saw a few performances from way late in his career and he had a confused, wide-eyed look that I recognized from visits to old-folks homes. It didn't feel right that he was still performing... like he didn't really know what he was agreeing to.
3. Modern Robert De Niro - His name in the credits will put me right off of seeing something at this point.
