Desi Arnez cameo appearance

NOt likely,

Although his family came to the United States in 1933, but from what I can find he was on the East Coast ny/miami until 1940.

The full cast and crews lists even the actors for the hot dog vendor so I would imagine that if he did, it would have been listed

He would have been 19 at the time.

Okay, here's another one: Spencer Tracey's office boy looks like Andy Warhol.

I think it was clearly Desi.

Circumstantial evidence: he was already becoming well known, having worked for Xavier Cugat, who had certain informal Hollywood connections, and within a year's time Desi would begin his own band; Latin band leaders were in strong demand in the 1930's and his appearance would have been interesting and fun to those in the know; and 10 years after this movie, MGM remade it, with Lucille Ball in the Harlow role.

Circumstantial, suggestive, not conclusive.

But using my own eyes, I say Desi was the elevator operator. I noticed it myself watching the movie this evening, before I read these posts.

I just watched this tonight; went back and paused to look at the elevator operator. No way this is Desi Arnaz. (stronger words withheld).

The elevator boy is played by Buddy Messinger who made a career out of playing bit parts as bellboys, clerks, ushers, messengers, mail deliverers, office boys, and he played elevator operators no less than ten times.
