I like her but I know she can be a bitch. A friend was in the ensemble of APPLAUSE when Bacall took out the first national tour following her stint on Broadway. He said she could be difficult and snooty if she didn't like you.
Forgot to add-- on stage she was wonderful. In both Cactus Flower and Applause. Unfortunately she was a bit over the top in the TV version of Applause. But on stage at the Palace.. she was a 'star.'
I don't like her old movies, I'm not much of a Bogie fan either. I thought her fame was mostly about being Bogart's widow and being exceptionally pretty. It was her Doris Duke miniseries that convinced me she can be a powerful actress. I wish Lifetime would replay it, I'd record if if they did. But I probably saw their last airing of it about 5 yrs ago.
