People these days are not so familiar with original expression that led to the title of this movie: "In like Flynn".

Indeed. When I first watched it on tv as a child, I had no idea what the title was supposed to mean. That’s a good link. Ironically, I think since 1967, more people are probably familiar with the term “In Like Flint” than “In Like Flynn”.
