La Fine Dell'innocenza - Annie Belle (1976) - Furama Hotel, Central

The hotel that the pair are staying at is the Furama. Built in 1973, demolished in 2001 and was replaced by the AIA Central building (it used to be AIG Tower but has since been renamed). It was a popular hotel with its top floor revolving restaurant (see the lowest images). One of the things I didn't know about it was that it had a carved replica of the famous "87 Immortals Painting" above the front driveway. This was based on a famous Tang Dynasty silk painting (you can see an image of it the painting here). In 1976, the management of the hotel was taken over by Intercontinental, which is why you can see the name in the screen cap below.

I don't have any stitching software on my laptop here in London, so here is my compromise below, showing the hotel in some of its former glory.

They also shot scenes in the revolving restaurant and in the hotel lobby.
