Sad news. When I was a kid I loved the Superman movies, and Hackman was so funny in those. The first time I saw The French Connection I almost had a heart attack during the classic chase scene, it was so intense. May he rest in peace.
Speaking off the cuff here, I have seen situations where a contractor has come in to work on the fireplace and didn’t do something correctly with the exhaust or venting of the fireplace or the gas stove. Carbon monoxide`can built up and get the entire household unless someone catches it.
Had a friend wake up and go to the bathroom and noticed as he looked in the mirror that his skin was green and that started things rolling. He woke up the family and saved everyone’s life. Everyone had bad headaches for a day or two. Stove had been worked on that morning and wasn’t venting properly.
My favorite as a teen was Poseidon.
