Petulia - Archie's Apartment, Interior
There were several scenes in the movie in Archie's apartment, all filmed on location at 307 Filbert Street on the Filbert Steps. In order to have a large enough space for the shoot the adjacent second floor apartments, B and C, were combined into one by opening a wall between them.
Then ... This panoramic composite captures Archie's living room with the front door to the right. Appropriately for a bachelor, there's a tiny kitchen, This is apartment C of 307 Filbert.
Then ... this is a view from the same living room looking towards the front door. Archie's bedroom is seen through the wall opening exposing the adjacent apartment B.
... and Now, the same apartment C view today with the wall opening filled in, back to normal.
Then ... This view shows Archie up in his loft.
Then ... And this is what Archie sees looking down from the loft to Petulia who has spent the night in his bed.
Then ... And finally, here's a view from the bed looking towards the wall opened up for the movie, with apartment C visible through it.
