Behind the scenes
Rosie Carver is Bond’s first on-screen black love interest. Her character was initially written as a white woman (and the lead Bond girl, Solitaire, as black) before the producers made the switch. During filming, the producers actually thought about sparing Rosie, but ultimately they went ahead with the original plan and killed her off.
