The Unfaithful (1947) with Zachary Scott and Ann Sheridan was another film shot in Bunker Hill.
Glenn Ford and Ricardo Montalban on stakeout in the 1966 noir The Money Trap. This was one of the very last film noirs to be made. The house they are surveilling is the Brousseau Mansion at 238 S. Bunker Hill Ave. By this time redevelopment had cleared most of Bunker Hill and this was one of the few remaining old houses.
The Brousseau Mansion had been built in 1878 by the family of the same name. By the 1940s it had been converted to a rooming house and was torn down shortly after filming of The Money Trap.
This clip from The Unfaithful shows how the hotel scene is played out as Zachary Scott and Steven Geray drive to the Hotel Elmar on a foggy morning.
