Walking through Venice on a cold February morning, I saw a row of houses along the Grand Canal which I thought I had seen before. It was my first day in Venice, I don’t believe in reincarnation, so my recollection must have come from a film.
And indeed: This is where the ultimate fight in the James Bond film Casino Royale takes place and one of the houses slowly sinks into the water.
You will notice that the red house (second from right in the two first photos), which stands conveniently apart from the houses to the left and right of it, has been replaced by a fake house in the movie. So, you needn’t worry! No real Venetian house was destroyed for this movie.

Next you’ll tell me that James Bond isn’t real, either?
He is definitely more real than a lot of other people/things/creatures that billions of people believe in.

Why would anybody do that, when they can simply go outside and meet people in the park?
The collapse is so convincing. I have been in St Mark’s square but I cannot recall any perspective that shows a row of palazzos like those in the movie.
The original James Bond books/films were in fact based on a real life person infact it was was Ian Fleming who was a British spy during ww2
