There's a TCM podcast called The Plot Thickens [0], season 1 of which was all about Peter Bogdanovich and well worth listening to if you're at all interested in the man or the auteur years of Hollywood. I'd also recommend Peter Biskind's Easy Riders Raging Bulls [1], one of my all time favourite books.
Anyone who's interested in more indepth information on him and on why his career and creative powers fell apart so swiftly after "Picture Show" would be served by reading "Hollywood: A Third Memoir" by Larry McMurtry (author of "Picture Show")
His story is a reminder of how a director is not an island, and his arc has some rough similarities with George Lucas's.
Swift decline ≠ immediate decline. Paper Moon came out 2 years after Picture Show, after which most of what he made was unwatchable by near unanimous consent. If that's not a swift decline I don't know what is.
After watching that film so many times as a child, on my first visit to San Francisco I was astonished to see how much of the city hadn't changed since 1971.
I also made my hosts take me on a pilgrimage to the stairs at Alta Plaza Park, the damage done to which during the filming of What's Up Doc is still visible. IIRC, Bogdanovich didn't request permission to film that scene on the steps, and was to be charged with vandalism if he made himself a nuisance in the city again...
One of my favorite long “podcast episodes” is this 3.5 hour collection of interviews between Orson Welles and Peter Bogdanovich. Really interesting discussion between two film greats:
Two years later, backed by Corman, Bogdanovich wrote, directed and appeared in his first film, Targets, which starred Boris Karloff, who owed Corman two shooting days.
Ok, but please don't post unsubstantive comments like this to HN.
You can either learn something about who he was or—if you don't want to do that—there are plenty of other things to read, some of which you may find more interesting.
