First up, the following suggestion is no help, but...
I've heard good things about
David Stratton's (<---linky) autobiography/memoir,
I Peed On Fellini (<---linky...BTW, the title is quite literal). David is Australia's pre-eminent movie critic. I don't know if it's available in ebook form.
Sorry this isn't what you asked for. Perhaps one for the TBR list?
Cheers,
Marc
