Daniel Craig initially rejected the part of James Bond, as he felt that the series had settled into a standard formula. He changed his mind when he read the finished script. Timothy Dalton had turned down 007 - Somente para Seus Olhos (1981) for the same reason, and, like Craig, ended up playing a different, more grounded interpretation of Bond in 007 - Marcado para a Morte (1987) and 007 - Permissão para Matar (1989).
In the shower scene, Vesper (Eva Green) was originally scripted to be wearing nothing but her underwear. Daniel Craig argued that Vesper would not have stopped to take her clothes off, and the scene was changed.
To prepare for the role, Daniel Craig read all of Ian Fleming's novels and talked with Mossad and British Secret Service agents who had served as advisers on Munique (2005).
The car barrel roll stunt by the Aston Martin DBS broke the world record for the most barrel rolls assisted by a cannon. Originally, the racing specifications of the DBS meant that a standard ramp would not be sufficient to get the car to roll, so the special effects team were called in to install an air-powered cannon behind the driver's seat. This allowed the car to complete seven full rolls. The stunt was officially entered into the Guinness Book of World Records on November 5, 2006.
