While it was hardly a secret what had happened to the Indianapolis prior to
Jaws, it wasn’t until the film’s release in 1975 that it became common knowledge.
The origins of the speech come from Howard Sackler, a Pulitzer Prize-winning playwright who worked as an
uncredited writer on the film. Sackler was adamant about explaining Quint’s blind hatred for sharks, and pitched the idea of making Quint a survivor of the disaster. Spielberg was receptive to his proposal, but after Sackler came back with just a single page of dialogue, it was left to another of the film’s uncredited writers,
John Milius, to expand. Clearly this was a job he took very seriously given that he came back with a 10-page soliloquy more fitting for a one-man stage production than a film – a concern Spielberg raised despite enjoying his work. In the end it was Richard Shaw who had the last word, rewriting much of Milius’s contributions until he landed on the final version.
