A letter from François Truffaut to Jean Renoir, telling the old master how much The Rules of the Game meant to him. Truffaut had lovely handwriting, I think, and made use of it in The Wild Child, where we see him, as Dr. Itard, writing in a journal about Victor’s progress, or lack thereof.
Truffaut wrote thousands and thousands of letters; he seems to have found it easier to speak his mind, and heart, in letters than in either phone calls or face-to-face meetings. Had he lived in the Age of Email I am certain that he would have continued to communicate by handwriting.
