Jeff Chandler's relationship with the older couple

Oh, no, I don't think that was ever meant to be implied at all! (Though I personally imagined that Cecil Kellaway's character was gay and didn't mind getting an eyeful of Jeff Chandler---ha!)

Rather, I just took it that they were a pair of grifters, a mature couple who "sponsored" young good-looking men by providing them with some living expenses. Of course, this sponsorship came with the understanding that the young men would romance/seduce older women in order to fleece them of some money, which would then be turned over to Osbert and Queenie.

It's really a rather surprisingly sordid set-up! You can see that by the mid fifties the production code was breaking down and Hollywood filmmakers could get away with a lot more than they would have been able to do just a few years earlier.

I thought Jeff Chandler was sponging off the couple because he sure made himself at home everywhere he went. But of course he is replaced by another beach-bum once Jeff Chandler takes up with Joan Crawford. So it seems as though they wanted a younger man to get introduced to wealthy widows.
