The Scavengers - Vince Edwards (1958) - Astor Hotel, Tsim Sha Tsui

Marian (Carol Ohmart) is staying at the Astor Hotel. We know this because we are told by O'Hara at some point in the story. The film did use that very hotel as well, although you never really see the name properly despite it being emblazoned across the main entrance to the hotel in neon light.

The hotel was located on the corner of Carnarvon Road and Cornwall Avenue. Sadly the latter street was obliterated when the K11 Masterpiece was built and there is no physical trace of it anymore, other than an open, nameless thoroughfare alongside the skyscraper where the street used to be.

In the first two images below Vince Edwards is standing on the corner of Bristol Avenue,with the hotel entrance on the corner of Cornwall Avenue. Carnarvon Road runs along left of frame where the cars are lined up.

The hotel makes a final appearance at the end of the film and although Allison's arrival there looks to have been filmed on location, his departure soon after (right at the end of the film) looks to have been filmed on a set.
