I can only remember one scene from this film, I think it’s fairly early on, perhaps even the opening sequence. A man in an airport lounge buys 2 copies of a newspaper, then sits at a table for (presumably) a couple of hours and solves the crossword puzzle. Then he gets up, throws the newspaper away, sits down at a different table opposite a girl, and solves the crossword puzzle again, this time in a couple of minutes, in order to impress the girl.
I think the film is from the early 1970s, I had always thought it was the Thomas Crown Affair but I watched that last night (1968 version) and that scene isn’t there.
If anyone can help identify the film I’d be very grateful, thanks.
