There is popular lore that novel Leaving Las Vegas was author John O’Brien’s “suicide note,” and that he killed himself upon learning that his book would be made into a movie. The idea of Leaving Las Vegas being a suicide note unintentionally originated with a letter O’Brien’s sister Erin wrote to Nicolas Cage after John O’Brien’s death, and with a New York Times article that claims his father also called the book his suicide note. It’s an poetic idea, but it seems to oversimplify the life and literary ambitions of John O’Brien.
