Holywell beach will become a Korean battlefield
Holywell Bay beach, near Newquay, is to be transformed into a North Korean battlefield for the film's opening sequence.
Production personnel are in the area for the two nights of filming planned for later this month.
Film-makers Eon Productions have already said they will be using the massive greenhouses of the Eden Project complex, near St Austell, for some scenes.
It is not the first time the surfer's paradise has been picked for film action - it was the setting for part of the Val Kilmer film Top Secret.
Holywell Bay life-saving club chairman Peter Herman said he had been told their headquarters would be turned into a pill-box for the sequence.
A small forest of trees would also be planted behind the dunes for the scenes, which would involve explosions and a commando-style assault.
It is understood that a stunt double will stand in for Pierce Brosnan, starring in what will be the 20th Bond spectacular to be made.
Other locations used in the as yet untitled film include Hawaii, Iceland, Spain and London, shooting began last month at Pinewood Studios.
