Airport by-play...

I'm pretty sure the comedic tit-for-tat engaged in by Kenyon and Rita in the airport and then on the plane has been lifted from another film, unless, of course, it was vice-versa. Unfortunately, I don't have an inkling even whether it was a British or American film.

Another point of interest was the ease with Roger, the brother, handled the drugs package, supposedly weighing over 30 lbs. He literally lobbed it over an 8 foot high gate.
