Deathbed Confession: He didn’t say anything, but he left behind a bunch of old film reels

I'm calling this a deathbed confession, but in reality when this director died a couple of years ago, he didn't say anything, but he left behind a bunch of old film reels from some of his movies, including several from the first installment of his most famous movie. Prior to the internet, everyone who discussed the movie did so probably without actually having seen the movie. What were people dying was actually the work of actors and some not very good editing and camerawork.
