A little of Loretta Young (featured this month on TCM) goes a long way at the Daily Mirror HQ, but I noticed these shots of a department store in “Employees’ Entrance” and they reminded me of the sequence in “Public Enemy,” which was identified as being filmed at the May Co. These light fixtures certainly look familiar.
Hm. Is that an escalator in the middle-left?
There’s the escalator and there’s the May Co.’s clock!
Now was this the May Co. or a set? Time for more detective work.

My guess is that the first shot is a background plate shot on location. The second, with little Miss Young on the escalator used the background plate, rear projected, on a stage that had a prop escalator in the foreground. The third shot looks like a sound stage with props and set pieces to suggest it is in the big store.

Typos are in my soup. The last sentence above should read the “The final shot…”

Remember what critic Dorothy Parker said about Loretta Young? “Her acting runs the gammet from A to B” and “Whatever this actress never had, she still hasn’t got it”.

Well, actually, “Her acting runs the gamut” was Parker on Katharine Hepburn. “Whatever it was that this actress never had, she still hasn’t got it” is Bosley Crowther on Young. (First occurrence George Eells “Ginger, Loretta and Irene Who?” 1976.)

Love Loretta Young. She certainly had something. Was watching her last night in “The Bishop’s Wife”, great Christmas fare, and she was totally entrancing and engaging.
