Surely you've seen
Pillow Talk? Doris Day is Doris Day, Rock Hudson is a songwriter who woos women with a heavily recycled song*. Okay, maybe you haven't. It's a romantic-comedy: they meet, fall in love, etc. The movie is of its time, but so is how they meet. Ma Bell can't lay down phone lines fast enough to meet demand, so the two had to share, thus providing some forced interactions when they want to use the phone at the same time. The romance doesn't proceed in a straight line from there, but it's the start.
The exercise is: give this movie the You've Got Mail treatment. How could it be modernized? What's an in-demand consumer product that could serve as a foil for Romance? Extra credit for updating the careers of the leads (interior decorator, Broadway composer).
