I’ve read many books about bad movies: all the Medved’s books, “Bad Movies We Love” by Margulies and Rebello, “The Worst Movies ever Made, or What Were They Thinking?”, and probably a couple of others. Any other ones I should know about?
John Wilson’s The Official Razzie Movie Guide: Enjoying the Best of Hollywood’s Worst.
Tim Healey’s The World’s Worst Movies has most of the usual suspects, but is worth it for the photo captions alone.
Mike Nelson of MST fame has written at least one fun book on bad movies: Mike Nelson’s Movie Megacheese. He’s also got a few others out on random topics.
Roger Ebert has a book called, “I hate, hate, hated this movie.”
