There's an English language version published by Da Capo, which unfortunately doesn't include many of the photographs from the original French edition. I have the French edition and read what I could before I gave up. My ideas are greater than my reality, but I still had all of the photographs. I once almost bought the French edition of Francois Truffaut's correspondence when I saw it in a book store in Cambridge, Ma. I thought I'd be able to translate it bit by bit. Glad I waited for the English translation which was published about two years later. Your English seems very good, so perhaps adding the Da Capo edition would be a good bet for you.
