This would be a translation of a book that appeared in France a few years ago, a compilation of interviews that originally appeared in Positif, the French film magazine.
Wilson, or Michael Henry as his name appears in Positif, has come to be just about Clint's favorite interviewer over the last couple of decades. I tried but failed to get hold of the French edition last year (it seems to be out of print). I wonder if Wilson went back to the original English versions, or if the work is back-translated from the French versions as published?
