IMDB Trivia: Casino Royale

"Reportedly, the name of Casino Royale's Vesper Lynd character [played by Eva Green] has two sources. First, she was named after an exotic cocktail called a "Vesper". The rum punch drink contains ice, rum, fruit and herbs and was served to Fleming and life-long friend Ivar Bryce at a north-eastern Jamaican plantation house. The other source of the name was apparently a spy friend of Ian Fleming called Christine Glanville, aka "Vesperale". She was allegedly a spy who had loved him."

Acchh, Moxie writhes in pain over the incandescent beauty of Eva Green!
