Where are these locations?
CitySleuth found and posted most of the locations in the 1950 movie The Man Who Cheated Himself but has drawn a blank on three of them. This is your chance to be a location sleuth - does anyone amongst you, dear readers, recognize them? If so, please contact email@example.com.
Often it turns out that hard-to-find San Francisco locations have been filmed elsewhere, usually Los Angeles. Or in a studio back lot. So bear that in mind!
1. Lois's place (UPDATE - CITYSLEUTH HAS FOUND THIS LOCATION)
The door number says 2370, but this may be fictitious (IT WASN'T). The style of house isn't typical San Francisco (SURE ENOUGH!) and CitySleuth has seen a reference to Los Feliz being used for a filming location for this movie (THAT'S WHERE IT TURNS OUT TO BE!). The street lamp looks very similar to those still found in Los Feliz. Could this have been there? (YEP!).
Then ... in the movie ...
... and Now, CitySleuth spent an afternoon on Google Street View checking out all of the homes in Los Feliz with house # 2370 and bingo, there it was. Supposedly in San Francisco but filmed at 2370 N. Vermont Avenue in Los Feliz, Los Angeles (map). The flimsy balcony supports flanking the front entrance are still there as too is the old street lamp. A low wall has since been added in front of the house.
These next two locations are still to be found ...
2. Andy's Place
It's unusual to see an entrance with a drawbridge but this place, on a steeply sloped street, has one.
3. Ed's place
This building has similar brickwork to Andy's place but that could be coincidental.
