According to Honor Blackman (Torygraph) Goldfinger took 4 weeks to film and she never got further than Northolt.Everything got filmed (quite convincingly) atPinewood. These people are just too pampered! 
All her scenes were in bed or at dining tables.
SHe also flew several jets and led an airborne attack on Fort Knox as I dimly recall.
Quite clever in North West London!
