Title: John Wick
Passage: The premise for John Wick was conceived by screenwriter Derek Kolstad who began work on a treatment about a retired contract killer coming out to seek vengeance, entitled Scorn. After one month of work, he had completed the first draft of the screenplay and once he had addressed several issues he pitched the script to various clients, garnering at least three offers. When he first started thinking about writing the script, Kolstad was influenced by film-noir classics and the themes of revenge and the antihero and the occurrences of what may play out if ``The worst man in existence found salvation (...) When the source of his salvation is ripped from him (...) Do the gates of Hades open?'' For Kolstad, both Alistair MacLean and Stephen King were influences in the creating of the story of John Wick in terms of characterisation and world-building, stating, ``(...) MacLean could build a world, and King could surprise you by what the main character truly was capable of.''
