Most people doesnt see the difference betwen the real locations, only a few hardcore fans.
Do You really think that EON spend millions dollars for some fans?
thats a crazy idea...location shooting isn't about hard core fans its about realism and evoking a feel, Mission IMpossible used Prague to good effect, Bourne PAris and Moscow and I would take either Bourne film over DAD ....any day....
people travel more now, they watch far more travel programmes, they see home videos of foreign locales, it is more difficult to fool people....Montenegro is a very distinctive place, very tranquil with a very distinctive coast line, which is why i am abit worried about them not filming there, though I assume they will do some second or third unit stuff over the coast line...to get the right 'feel'....
and if you knew anything about film production you would realise shooting on location that ISn't the location you're supposed to be in is actually quite costly, hence the close quarter camera work and the rather obvious touches...BOurne makes full use of the locales, the characters are clearly where they are supposed to be...
the second unit stuff should be okay for Montengro and Madagascar,,,I will hope they have the sense to do that given how press attention has been given to WHERE they are...
