The Honeymoon Killers (1969), Leonard Kastle.

This movie purported to be a "documentary style," "anti-Bonnie and Clyde" type flick but all I could think was that the filmmakers were so contemptuous of their characters that they couldn't accomplish these goals. And not contemptuous because the two leads were murderers, but because like, can you believe that fat chick actually thought he loved her? Lookit that awful bathing suit hanging off her! Definitely not a fun, campy, proto-Tab Hunter/Divine vibe going on here.

Also makes absurd use of Gustav Mahler which means that this movie has something in common with Rubin & Ed.

The Devil's Candy (1992), Julie Salamon.

In 1990, Brian De Palma attempted to squeeze Tom Wolfe's humongous satirical novel Bonfire of the Vanities into 2 hrs of film. Julie Salamon, who had previously worked as a film critic for the Wall Street Journal, was given full access to the set and all players involved in the production while writing The Devil's Candy. Who knew that this movie would bomb so hard, making her book a classic work documenting how dysfunctional Hollywood can be. Salamon takes a completely objective point of view, giving a complete 360 of the production. Her detached perspective makes it difficult for the reader to assign blame to any one person or point to one main reason for the disaster. Her peek into the eccentric habits of actors and production folks is fascinating, and just adds to the fun of reading what is basically a list of dumb decisions.
