In 1962, Mankowitz offered to introduce his friend Cubby Broccoli to Harry Saltzman, holder of the film rights to James Bond, when Broccoli mentioned he desired to make the Bond series his next film project. Broccoli and Saltzman then formed Eon Productions and began co-producing the first Bond film, "Dr No", for which Mankowitz was hired as one of the screenwriters. After viewing early rushes, Mankowitz feared that the film would be a disaster and damage his reputation and insisted on having his name removed from the film's credits. He later also collaborated on the screenplay for the non-Eon 1967 Bond movie, "Casino Royale". He wrote the script for Yorkshire Television's serial "Dickens of London" (1976) and the book of the same name based on his research when writing the series.
