 Harwood stated in an interview for "Cinema Retro" that she had been a screenwriter of several of Harry Saltzman's projects, and her screenplay for "From Russia with Love" had followed Fleming's novel closely, but she left the series due to what she called Terence Young's constant rewriting of her screenplay with ideas that were not in the original Fleming work.Maibaum kept on making rewrites as filming progressed.Red Grant was added to the Istanbul scenes just prior to the film crew's trip to Turkey; this brought more focus to the SPECTRE plot, as Grant started saving Bond's life there (a late change during shooting involved Grant killing the bespectacled spy at Hagia Sophia instead of Bond, who ends up just finding the man dead).
