If Those Walls Could Only Talk

Spencer Tracy welcomes Bob back from the war and points out Bob's old dressing room awaits him.  I'm sure there was quite the pecking order among the stars, including the women, as to the dressing rooms they were assigned.  Besides, of course, Marion Davies for whom Daddy built her own building on the lot.

Bob comes back to a floor of new neighbors.  Robert Taylor is still in the service, replaced temporarily by Walter Huston.  Tracy has moved to the first floor to take over Nelson Eddy's vacated apartment - his contract was not renewed in 1942.  Fred Astaire is on the lot while making The Ziegfeld Follies and Yolanda and the Thief.  Lionel Barrymore has relocated to the first floor because of his severe arthritis, making room for Edward G. Robinson who filmed Our Vines Have Tender Grapes at MGM.

And Donald Loomis ... as in, who the heck was he that he had an apartment among the top men stars at MGM in 1937??  I did finally track him down.  He was the personal trainer for the stars, located there for their convenience, I assume.  An interesting job for sure!
