ABC 20-20 Friday night covered the mother-daughter relationship between Debbie Reynolds and Carrie Fisher, as with this link.
Carrie Fisher had a cardiac arrest on a flight to Los Angeles from London, 15 minutes before landing. Nearby passengers tried to do CPR, which presumably flight attendants know how to do. It’s a good point to wonder, how many of us are prepared to do this if called upon suddenly.
Reynolds went into a fatal stroke the day after her daughter’s death. Stress hormones in her cardiovascular system from grief probably caused the stroke.
I probably saw “Singin’ in the Rain” as a child, but I actually remember “The Tender Trap” (with its now outmoded idea of heterosexual romance and of women) and particularly “Susan Slept Here”.
