The Bogart biography by Sperber & Lax and By myself and Then Some by Lauren Bacall both narrate with minutia his last years (friends gathered at his butternut room, The Rat Pack leaded by Frank Sinatra - who wooed Bacall and retracted later - his brave and silent fight against esophagus cancer, his children Stephen and Leslie). Bacall's memoirs book is an excellent recount of her romance with Bogart. "Never damage your own character," he taught Bacall, "Bogie, with his great ability to love, never supressing me, helping me to keep my values straight in a town where there were few, forcing my standards higher - To be good was more important than to be rich. To be kind was more important than owning a house or a car. To never sell your soul was most important of all".
Bogart is one of my best celluloid crushes, he embodies in the purest form a portrayal, a past master, the stuff that dreams are made of (a line he suggested to Huston for The Maltese Falcon).
