 Broccoli had originally hired Richard Maibaum and his friend Wolf Mankowitz to write "Dr. No"s screenplay, partly because of Mankowitz's help in brokering the deal between Broccoli and Saltzman.An initial draft of the screenplay was rejected because the scriptwriters had made the villain, Dr. No, a monkey.Mankowitz left the film, and Maibaum then undertook a second version of the story, more closely in line with the novel.
