Just because he said forty years doesn't mean he's not a fan. I don't mind if he isn't a fan, hopefully it wont affect the movie. But he may be fan and just, I dunno, said it like that for some reason. It's sometimes what I do, i think right this started in the seventies, it's been forty years since the start of the seventies etc...
Did that make any sense because I've just read it back and it sounds weird.
