While I was composing the review of Some Like It Hot I often thought of Lemmon and Curtis in The Great Race, which is my favorite comedy film. In The Great Race there's scene that I think may hold an inside joke. In The Great Race Jack Lemmon plays two roles: the dastardly villain Professor Fate and the always-slightly-inebriated Prince Hoepnick when the story reaches the fictitious European kingdom of Pottsdorf. During the Pottsdorf period there is a dance montage that may hold a quick reference to Some Like It Hot. https://www.youtube.com/watch?v=1Bk6aMNCNko (The uploader edited the soundtrack, which is why it seems to change quality in the middle.) The joke buried here is quick and difficult to spot (one of my daughters actually first noticed and brought it to my attention). At about the one-minute mark, just after Hezekiah and his dour-looking matronly partner do a couple turns, the next shot widens to the entire dance floor. Curtis is seen spinning with his new partner, a woman in a pink gown, and behind them is Lemmon, now dancing with a male partner. As they twirl past Curtis, he seems to look toward the off-camera crew, his expression almost as if to say "that's not the way it happened during rehearsals!" He genuinely seems surprised. As he looks back at Lemmon again you can see the woman in the pink dress seemingly trying hard to keep from laughing out loud. I just wonder if Lemmon weren't pulling an inside joke here, perhaps mocking his dance scenes with Joe E. Brown the last time he and Curtis had worked together and Blake Edwards just went with it. There is, of course, no way to know, but I find the thought amusing.
